Verify the results of give problem using the VPULSE function and the appropriate initial current.
Problem
The switch of given figure has been open for a long time. It is then closed at t = 0 s.
a. Write the mathematical expression for the current iL and the voltage vL after the switch is closed.
b. Sketch the waveform of iL and vL from initial value to the steady-state level.
A modulator transmits symbols, each of which has 64 different possible states, 15,000 times per second. Calculate the baud rate and the bit rate.
Explain the major differences between a motor and a generator. Explainin detail how the simple motor worksand be sure to include the functions of the reed relay and transistor.
Two friends A and B meet every morning at the Grand Central Station around 7 am. Suppose the actual times they arrive are independent and uniformly distributed between 6:55 am and 7:05am.
Explain the difference between hard-decision and soft-decision decoding in partial response signaling, including the relative advantages and disadvantages of each.
