Define Sampling Frequency?
Since real analog signals consist of several frequencies, spectrum of the input signals should be limited to make sure that no signal energy exists above a fixed frequency. After that a safe sampling frequency can be calculated.
In use, an appropriate bias voltage is applied between the two bases, with B2 made positive with respect to B1. Because the N-type bar is resistive, a relatively small current will
Q. emf produced by windings? The time variation of emf for a single conductor corresponds to the spatial variation of air-gap flux density. By suitable winding design, the harm
In a CDMA system, the signal is spread over a large bandwidth by multiplying the transmitted symbol by a sequence of short pulses, also called chips. The
Explain Mobility . Average drift velocity of electrons (e - ) in an applied field is proportional to the field, the absolute magnitude of the proportionality factor eq/m, termed
Requirements of equalizer connection
Consider the magnetic circuit of Figure with an air gap, while neglecting leakage flux. Correct for fringing by adding the length of the air gap l g = 0.1 mm to each of the other
Q. What is meant by biasing transistor? The purpose of dc biasing of transistor is to obtain a certain dc collector current at a certain dc collector voltage. These values of c
Q. Determine voltage and current gains for the CE BJT amplifier shown in Figure with the following parameters: R 1 = 30,000, R 2 = 9000 ,R C = 750 ,R E = 250 , R L = 1000
Aloudspeaker is a common electrochemical transducer in which vibration is caused by changes in the input current to a coil which, in turn, is coupled to a magnetic structure that c
