Transistor switching times: The turn-on time of switching transistor sum of delay time (td) and rise time (tr). ton = td + tr. Delay time (td): It is defined as the time during which the collector current rises from zero to 0.1ICS.

Dancy met Claire Danes on the set of Evening and they began dating after filming concluded. In February 2009, they announced their engagement. It was reported that the couple were secretly married in France in early September 2009. so yes hes married .

You can use a second gate on the same IC to invert the output (most OR-gate ICs I know of have 4 gates per chip). Do this by tying the output of the first gate to both inputs of the spare gate.

Your question presupposes that you have subscribed to cable internet service, and that the provider has run a cable to your home. It also presupposes that you have a cable modem. If these suppositions are correct, you just have to run coax between the cable jack on the wall and the cable modem. Then you need to connect the modem to your computer via USB, FireWire, or whatever interface your modem and computer have in common. FriPilot

Video Search engines - A video search engine is a web-based search engine which crawls the web for video content. Some video search engines parse externally hosted content while others allow content to be uploaded and hosted on their own servers. Some engines also allow users to search by video format type and by length of the clip. Search results are usually accompanied by a thumbnail view of the video. www.blinkx.com/ - was launched in 2004 and uses speech recognition and visual analysis to process spidered video rather than rely on metadata alone. blinkx claims to have the largest archive of video on the web and puts its collection at around 14,000,000 hours of content. www.altavista.com/video/default - had one of the first video search engines with easy accessible use. Is found on a direct link called "Video" off the main page above the text block. www.truveo.com/ - is a Web-wide video search engine that was founded in 2004 and launched in September 2005. Truveo claims to index over 100 million videos from thousands of sources across the Web From wikipedia Zeropaid.com is all about p2p, file sharing, digital media and technology. We provide guides, a comprehensive list of file sharing programs with user reviews and ratings, fresh daily technology news, and informative discussion forums

Depends on the types of logic gates you're drawing. They have different symbols. You should be able to search the web for a list of symbols for the various gate topology. Using smartdraw tool, you can drag and drop such ready made shapes.

Corel draw graphic suite is another such tool.

That title of "Universal Gate" is reserved for NAND gates because you can build all possible logic using only NAND logic . You can build even other basic logic like AND, OR and NOT using NAND.

The set top box that your provider gives you is what converts the Digital signal to the analog signal.

The digital signal is compressed at the provider and sent to the end user. The "tuner" (which can be built into a tv, a set top box or a cable card) Then decompresses the digital signal and converts it into an analog signal.

There is much more to this did not know how technical you wanted your answer.

what is the idm serial number

Well luckily for you I'm working on a 2000 Bonneville non supercharged car right now. Same code... I can hear a hissing noise from the passenger side of the engine.... found the actual map sensor has come apart.... maybe this will be your problem. Good luck.

There is none. AOSS is a Buffalo Technology product, not Belkin.

1.) what is operating system? 2.) what an array ? how is an array different from ordinary variable ?

A laptop. It is also called a PC for personel computer.

Depending on the kind of programming they do, possibly almost all the time. I've worked for several major financial companies and we've used everything from high school algebra and trigonometry to create graphics software, up to doctoral-level math when we did probability and statistics. My nephew programs games and he uses all sorts of math to make the the look and behavior of the characters appear realistic. He has to worry about everything from how a ball behaves when it bounces, to how light reflects off a surface.

AND gate is an all or

nothing gate because in able to have an output of logic 1,all of the input must be all logic 1 or else the output will be nothing or simply logic 0.

The inverter, which returns the reverse of the input. The AND gate which returns a high output if and only if both inputs are high. The OR gate, which returns a high output if either or both inputs are high. The NAND and NOR gates return the opposite of their counterparts. They are basically the AND and OR gates with an inverter after them. The XOR gate is the exclusive OR gate; it returns a high output it either input is high, but not both. Every binary combination of outputs can be made from these operators. In fact, you don't even need all of them. The NAND and the NOR gate can both create every other gate.

XORing X with 1 gives X', i.e., NOT(X). If we are able to construct a NAND (AND) using XOR, we can also obtain AND (NAND) from it, which makes XOR a universal gate since inverted inputs to a NAND (AND) will give OR (NOR). However XOR is not a universal gate! Therefore we cannot obtain NAND (AND) using XOR. :-)

You need to make a distinction between analog and digital signals, and analog and digital data. Digital data can be sent on an analog signal by using a modem. Digital data sent on a digital signal is done over a wire using voltage pulses at two or more levels. Digital signals can't travel very far without amplifiers, but analog signals can cover huge distances, such as with satellite communications and even communications with deep space probes.

The 74LS00 is a logic NAND gate with normal logic level inputs. This means that the inputs has a low range below 0.8V, unrecognised range and a high range above 2V. At any time a input signal crosses those levels, a change in state can be expected. Applicable to the LS family, they have a floating input that means it is uncertain the state of logic level if no input is connected. Therefore never assume that since the input is not connected that the circuit will assume a zero, it can be either zero or one.

The 74LS132 is also a NAND gate logic function. But different to the Logic level input it uses what we call a Schmitt trigger input to improve noise immunity in a circuit. In simple terms; it's really nothing more than a comparator input. But the Schmitt trigger also have a hysteresis, which help to eliminate the affect what noise have on the circuit.

On a more technical note

Each circuit contains a 2-input Schmitt trigger followed by a Darlington level

shifter and a phase splitter driving a TTL totem pole output. The totem pole is basically a push-pull output stage constructed with two p-n-p transistors and a diode on the output.

The comparator function would mean that there is a particular threshold level on the input and if the input voltage pass the particular level, the output or intermediate state of the function will change state. In the case of multiple logic inputs the change of input state does not necessarily mean a change in output state and therefore I will refer to an intermediate area inside the function related to the input state.

The hysteresis create a high and low trigger points. This cause the input to at least pass the high trigger point of about 1.6V before the intermediate state will change or drop below the 0.9V before the intermediate state change back again. Therefore the practical unit will not have one particular level to change state but these two fixed trigger points must be used.

It sounds like it complicates matters but it really helps to handle input noise signals which makes the Schmitt trigger a handy device. Making it a good device for signal conditioning of logic signals in some applications.

Also take note that the high and low hysteresis trigger points may vary with supply voltage. In fact I do not recommend it as standard practice to use a Schmitt trigger to evaluate analogue levels, some engineers may differ but I would rather refer to a real comparator circuit design where you have more control over precision, trigger points and reference levels. But may be considered for logic inputs from sensors or conditioning of logic signals

Some circuits may also employ Schmitt trigger devices for oscillators and contact debouncing

Logic Gates are electronic building blocks of a digital system.

Their physical manifestation may take any form, but essentially a logic gate consists of a collection of binary digits and a set of rules where such digits are combined to give a resulting set of binary digits.

The rules that are implemented by logic gate are of the fundamental Boolean Algebraic Operations.

Logic gates may be coupled together so that digital input to a system produces a predetermined digital output. It is a logical set of rules. The concept of digital information flowing into a system through an electronic pathway coveys a perception that gave someone the idea of a gate when this was named long ago.
