we have to do sampling in dsp because in dsp we have to convert all in analog signal in digital form so for converting into digital signal first we have to convert continuous tome signal into discrete time signal....so we use samplin in dsp...

How do you identify a particular feedback topology in a circuit?
For analyzing the feedback amplifier, it is necessary to go through the following steps. Step 1 : Identify topology ( Type of feedback) 1. To find the type of sampling network (i) By opening the output if feedback signal becomes zero, then it is called "voltages sampling" (ii) By shorting the output loop if feedback signal becomes zero, Then it is called "Current Sampling" 2. To find the type of mixing network (i) If the feedback signal is subtracted from the externally applied signal as a voltage in the input loop, it is called "Series Mixing" (ii) If the feedback signal is subtracted from the externally applied signal as a current in the input loop, it is called "Shunt Mixing" Thus by finding the type of sampling network and mixing network, type of feedback amplifier can be determined. for example, If amplifier users a voltages sampling and series mixing, then it is called a voltages series amplifier
How do i reset my Tork DG100 digital time switch?
Go to tork.com they have a tech page with all of your questions answered or you can call them and they will walk you thru reset step by step.
Difference between sensor and Acatuars?
A sensor is a device that is programmed to send a signal as soon as a specified event occurs; for example the motion sensor in supermarket doors. Meanwhile, an actuator is a device that does an especifc action according to a signal received. Lets go back to the door: Once the motion sensor detects a movements, it send a signal to a piston that moves the door. To sum up: sensors detect events and actuators perform an action
What would happen if the lead of your voltmeter were connected backward?
A digital voltmeter will read negative voltage, if connecting backward. If the meter is an analogue type, the needle will go backwards and dip below the 0 on the scale.
Why digital multimeter more accurate than analog multimeter?
An analogue instrument is analogous to the unit being measured. For instance, a thermometer uses a fluid, such as mercury, which reacts to heat, expanding and contracting, and thus providing a direct reading upon a calibrated scale. Similarly, a stadiometer measures a person's standing height by sliding an arm down a scale until it touches the persons head. In both cases, a reading can be taken directly off the scale, thus the scale is analogous to the quantity being measured. Digital instruments, on the other hand, must encode these analogue measurements into digital information. However, analogue information is infinite. That is, between any two fixed points upon a scale there are an infinite number of variables, just as the number of real values between 0 and 1 is infinite. Digital information cannot encompass the full range of infinite values, therefore digital information must employ a degree of precision; values must be rounded. However, humans do this anyway. If we're measuring distance in millimetres then we will round to the nearest millimetre. The amplitude of a sonic waveform at any given moment in time also has infinite range, from -1 to +1. When we digitise analogue audio signals we use approximation by scaling the analogue value to an integer in the range -32,768 to +32,767 (assuming 16-bit precision). This inevitably means some data will be lost. However, one hopes, the loss is so minimal that it will not be missed. If we need to capture the signal more accurately, we simply increase the number of bits to give a wider range of scaled values. So 24-bit would allow a range of -8,388,607 to +8,388,607.
Why scope frequency is always greater then signal frequency in the oscilloscope?
In the course of sampling a signal to graph the parts of a repeating event on the display, the sampling must be done faster than the event you want to graph. If the sampling is done slower than the event then you will be displaying several parts of the event in a single dot on the display, highly inaccurate. The signal sampling must be done fast enough to display the event in enough detail. The higher you set the scope frequency, the wider the event appears on the display, possibly losing the sides of the event if you go too high.
Which device is used to convert digital signals to analog signals or analog signals to digital signals?
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.
Will your digital television that's receiving an analog signal from comcast be a clear picture digital signal when you go digital in 2009?
Only if you have a digital output on your cable box. If not, it'll end up being a digital signal, converted to analog and then reconverted by your TV back to digital. Besides, the digital changeover date is only for local television stations when they turn off their analog transmitters. This means that if you currently have cable or satellite with analog outp[uts, that aspect of it shouldn't change.

How does modern work for computer?
you mean modem? MO-DEM MOdulation / DEModulation. It turns your digital signal into analog, so it can go thru the phone lines to your isp, and then from the phone lines to their server, it converts the analog signal back into digital.
How analog signals are different from digital signals?
An analog signal is a signal of varying amplitude. The signal can be: Light of different intensity Light of different colour Varying voltage like that produced by an MP3 player or Computer Soundboard. Varying levels of radiation We can easily compare the Analog signal with waves on the ocean. They go up and down and can vary in speed, size and intensity. Digital signals are very different. Digital signals are either on or off. In light, we either have light on, or we do not have light. Analog measuring is often a part of describing when a digital signal is a zero or a one. We measure for levels of light, or levels of voltage to define whether the signal is supposed to be interpreted as a zero or a one. This makes digital signals very resistant to background noise and they can travel very far with little or no degradation. Digital signals are very suitable for transferring information. This is actually what they are all about. Analog and digital signals go these days hand in hand when it comes to music. We transform an analog signal into its digital representation and by recording the digital information we do not get loss of information.
What is the digital channel for channel 4?
If you are in the USA, go to tvfool.com and click "signal locator". I know this sounds line a joke but is is NOT!

When to apply sampling?
you can use sampling when your population under study is large, expensive and time time consuming to study.... in a nut shell, when studying entire population is expensive we go for sampling...
Why do you go for digital image processing?
Lot's of photographers use digital image processing as opposed to old fashioned because you can do non-destructive editing and come back at a later time and make changes. Using the old fashioned way of editing (using film and chemicals), if you ie. overexpose part of the image, or remove an element, you are stuck with the changes you made.
Does Bose surround system work on Avol tv?
The Bose surround systems will work with any audio signal that has an analog or digital output. If you TV has that, then you're good to go.
Can you connect a 2nd TV to 1 cable box?
Yes. Just get a splitter. The only problem will be that you'll have to watch the same channel on the second TV as with the first TV. You might be able to split the signal before the cable box and just receive only the analog channels that the cable signal is carrying, but as they switch over to digital, that'll all go away on February 17, 2009 as televsion nationally, goes to an all digital transmitted signal.
