What is the impedance Z between terminals A and B of the networks shown below? Express your answers in polar form.
Three voltages represented by v1(t)=100cosωt, v2(t)=70cos(ωt-400) and v3(t)=60sinωt act together in the same circuit. What is the sum of these 3 voltages? Express your answer as a time-domain voltage.
A voltage v(t) = 200cos1000t is applied to a circuit, resulting in a current of i(t) = 10cos(1000t+ π/6). Determine the resistance and reactance of the circuit, the average power dissipated and the power factor.
a. Describe briefly with suitable diagrams, how power amplifiers are classified with reference to operating point? b. Get the maximum efficiency of class A direct coupled power
Q. What do you eman by Digital Circuits? The use of nonlinear devices (BJT and FET) in constructing linear amplifiers. Although these devices are inherently nonlinear, their op
WRITE THE PROCEDURE CONDUCT OC AND SC TEST OF AN ALTERNATOR TO FIND SYNCHRONOUS IMPEDENCE
Q. A source of impedance ¯ Z S = R S = 100 has an open-circuit voltage v S (t) = 12.5 cos ωot and drives a 75- transmission line terminated with a 75- load. Find the current
Design a low noise amplifier using an Infineon RF transistor BFP640. The amplifier is to be used to amplify the L2 GPS signal and so the centre frequency is 1227MHz and bandwidth 4
What are the basic modes of operation of 8255? There are two basic modes of operation of 8255, viz. 1. I/O mode. 3. BSR mode. In I/O mode, the 8255 ports work as progr
Q. Explain the Methods of Analysis for digital system? Just as differential equations are used to represent systems with analog signals, difference equations are used for syste
explain the properties and the application of high resistivity materials related with tunsten and carbon?
A common-collector (CC) amplifier is also known as an emitter follower (or a voltage follower) due to the fact that the output voltage "follows" the input by being approximately eq
