Assuming the zero state output of the DAC is 0 volts, then 4095 steps of 8mv would yield a full scale output of 32.76 volts. The resolution is one part in 4096, or 2.44 percent. An input of 010101101101 is 1389. Multiply that by 8mv, and you get 11.11 volts.
What is bias through selection and omission?
An editor can express a bias by choosing to use or not to use a specific new item. Within a given story, some details can be ignored, and others included, to give readers or viewers a different opinion about the events reported. If, during a speech, a few people boo, the reaction can be described as, "remarks greeted by jeers" or they can be ignored as "a handful of dissidents."
Bias through omission is difficult to detect. Only by comparing news reports from a wide variety of outlets can the form of bias be observed.
Advantages of hybrid modulation over digital modulation?

The trimmer resistor is a calibration device used to correct (trim) the resistance of some other resistor. An example might be the feedback loop of an op-amp in common mode. If you wanted a gain of two, you might use a resistor divider with a two to one ratio. Resistors have tolerance, however, so the stated value will not be exact. You place a trimmer resistor in series with one of the other resistors, picking the value so that, if the two other resitors were exact, the trimmer is set to midpoint, and that the trimmer's range covers the expected tolerance of the other resistors. Then you calibrate the circuit to the expected gain using the trimmer.
Why intrinsic semiconductor is not used in practical applications?
we dont get an appreciable current in dis case...dats why we dope n get curret for practical use...
What is the bandwidth of a circuit with a frequency of 3.7 mhz and a q factor of 250?
I came up with 14.8 khz, is this right?
What a few example of non linear resistance?
Two examples of non linear resistance is a diode and a light bulb.
What is the power dissipated by a 10 ohm resistor with 20 volts supply?
A 10 ohm resistor across a 20 volt source has 2 amps flowing through it. A 20 volt source providing 2 amps is producing 40 watts. Voltage is Resistance times Amperes
Watts is Voltage times Amperes
Alternative Answer
Divide the square of the voltage by the resistance.
Why is input resistance low and output resistance high in transistor?
The input resistance of a trasister is jst like pn junction of a diode which has a breakdown voltage of .7v for silicon and the output resistance is like a reverse bias of a diode and hence the resistance is high
Most common failure in a resistor?
This depends on the type of resistor. Carbon composition and metal film resistors typically will burn open, carbon film types can short.
What is power gain of an amplifier having input gain 20watt and output of 20mwatt is?
The power gain of an amplifier having an input of 20W and an output of 20mW is 0.001. Expressed in decibels, that is a gain of -30db. (log2 0.001 * 3)
If you meant an output power of 20MW (mega instead of milli), the gain is 1,000,000, or +60db.
The resistance that controls a heater motor in the electric system .
What is a Thevenin's equivalent circuit consists of?
A Thevenin's equivalent circuit is a single voltage source in series with a single resistor. It is electrically the same as any combination of voltage sources, current sources, and resistors that, as a black box, has two terminals. The technique is useful in simplifying circuits, when analyzing them.
You need more information than this to find your solution.
There will be a a value for the electric field at which point the air will break down. you also need the area of one of the capacitors and the capacitence
Concept of maximum power transfer in transmission line?
Transfer capability in transmission system defines the capability of system to reliably transfer power from one zone to other or from one part to other without affecting system stability. Under this concept there are various terms like Available transfer capability (ATC), total transfer capability (TTC), capacity benefit margin (CBM), TRANSFER CAPABILITY MARGIN (TCM). The term maximum transfer capability is termed as Total Transfer Capability means maximum power transfer from one part to another without violating system constraints.
Use commutating capacitor for bistable multivibrator?
it is about thefiltering of the ac signal from the circuit. when transistor2 switched on, collector terminal is suddenly shorted to ground and voltage at collector2 drops to vce from vcc.it cause a negative voltage pulse. the negative pulse coming at the collector of 2nd transistor passes to base of 1st transistor and thus transistor1 is switched off. commutating capacitors will allow to pass the ac signal only. so the negative pulse at the 2nd collector alone is feed to the base of 1st transistor. that is function of commutating capacitor
A dangerous circuit with low resistance and high current?
Another name for a circuit with low resistance and high current is a short circuit. It is dangerous because, if you have sufficient energy in the power source, you can damage components and/or cause fires.
a 7408 ic chip is a quadruple, 2 input AND Gate chip. These chips have 14 pins. Pin 7 is gnd and pin 14 is vcc. In principle, an AND Gate is just that. A gate that is Active high. To get an active high output, you must have both inputs active high. 5 volts on each input will give you a 5 volt output. These IC chip use TTL (transistor-transistor logic). They are obsolete and are no longer used in todays electrical circuits. Most electronic systems use a large CPLD, Complex Programmable Logic Device, that can be used to implement digital logic designs that contain 20,000 or fewer gates. Texas Instruments poineered the TTL 7408 IC chip. CPLD boards are commonly made by a company named Altera
Not 100% sure, but I believe it's the reverse current at which a Zener diode enters breakdown. There is also the Zener max current which refers to the current that must not be exceeded if you do not wish to damage the device and also the Zener test current at which the Zener Voltage is measured. The test current usually lies somewhere (roughly halfway) between the knee and max current.
What current is flowing if 0.67 c of charge pass a point in 0.30s?
Current = charge / time....so 0.67 c / 0.30 s = 2.23 A
Calculation of peak value for ac signal?
The peak value of a sinusoidal ac signal is RMS voltage divided by 0.707, or two times the square root of two.
Note: AC signals are rarely truly sinusoidal, because power supplies rarely pull a consistent load for the full duty cycle. (They pulse.) This introduces harmonics in the signal, which cause error in the above calculation but, unless the harmonics are extreme, the calculation is close.
Digital converter box say no signal how can you get signal?
If you have no signal coming into a digital converter box, you either have no service or you have a broken connection between the service provider and the box.
If you have no signal coming out of a digital converter box, you either have no service, or you have a broken box, or you have some kind of short on the output.
If you have no service, then you need to contact the service provider. If the box or the circuitry is bad, you need to fix it, or you need to contact the service provider.
Any other meaning to this question constitutes a request to know how to defeat the security of a digital converter box. That is an illegal activity, and WiKi Answers does not provide answers for those type of questions.
How do you say ZnO is n type semiconductor?
ZnO has an n-type character because of presence of nonstoichiometry that is absence of elemental composition that can be represented by a ratio of well-defined natural numbers.This n-type behaviour is due to point defects like vacancies and interstitials in the ionic crystal. An alternate reason presented , based on theoretical calculations is the unintentional substitutional hydrogen impurities in the compound.
