two identical CE amplifiers are connected in cascade. The first stage is fed with a source eVsig having a resistance Rsig= 10k ohms. A load resistance Rl=10K ohms and is connected to the collector of the 2nd stage. Each BJT is biased at Ic= .25mA and has beta =100 and a very large Va. Each stage utilizes a collector resistance Rc=10K ohms.
(a) Sketch the equivalent circuit of the two stage amplifier.
(b) Calculate the voltage transmission from the signal source to the input of the first stage.
(c) Calculate the voltage gain of thefirst stage, Av1.
(d) Calculate the voltage gain of the second stage, Av2.
(e) Find the overall voltage gain, Vo2/Vsig.
Draw up a flow chart for testing any four-terminal MOSFET with an ohmmeter which can be used to conclusively determine which lead is the gate, which lead is the body, whether the device is an n-channel or p-channel, and whether the device is a D-m..
Plot the magnitude response (in dB) and the impulse response of the designed filter using MatLab.
Design a digital security system for a four-door sedan car. There are sensors on all doors, hood, gas cover, and the trunk. When the car is locked, an alarm will sound if somebody tries to force open the door, hood, gas cover, the trunk, or tries ..
Write an assembly code for a subroutine implementing signed multiplication with Booth's algorithm. Make sure it works as expected. Compare it with your implementation of sign/magnitude multiplication from the second homework.
A company has 100 metal halides (400W each with 1.2 ballast factor) and four motors (each with 50 hp capacity, 95% efficiency, 100% load factor, and 80% power factor). The power factor for the combined load
