A simple power system consists of a dc generator connected to a load center via a transmission line. The load power is 100kW. The transmission line is 50km copper wire of 3 cm in diameter. If the voltage at the generator terminals is 400V,
compute the following:
a. Voltage drop across the load
b.Voltage drop across the line
c. line losses
d. System efficiency
With the 1s complement scheme, how does the receiver detect errors? Is it possible that a one bit error will go undetected? How about a two bit error?
Consider a signal x(t) = 10 cos(2pi*fct + 4 cos 2pi*fmt). Assume frequency modulation. The message frequency fm = 2:3 kHz. Calculate the modulation index and find the bandwidth when.
Describe your understanding of the similarity and differences between MOSFET and BJT, in terms of 1) terminal behavior, 2) i-v characteristics, 3) amplifier configuration, 4) small-signal equivalent models and 5) biasing technique.
Analysis of z transform to time domain, poles and zeros, From a given z transform X(z) = {1- z^-10}/{1 - z^-1} the discrete time domain form x(n) is deduced using complex manipulation and inverse transforms to arrive at x(n) = x(n-1) + u(n) - u(n-..
A sequential circuit has two inputs w 1 and w 2 , and an output, z. Derive a suitable circuit for the given condition.
For input signal voltages between these limits, the input should pass unaltered to the output. The peak current drawn from the input source may not exceed 1mA. You may use any circuit component we've studied except opamps.
What are the techniques used to make feedback system stable? Explain and draw the frequency response of a 1-pole feedback amplifier.
The ALU required for this lab accepts two 4-bit inputs (A0 - A3, B0 - B3), a 3-bit function selection code (F0 - F2) and outputs a 5-bit result (S0 - S4). Since the function selection uses 3-bits, there are 8 different functions.
Compute the amount of time required to deliver 10 frames to the receiver with stop-and-wait flow control. Assume that all frames and ACKs are received correctly.
1) A 1.5H inductor has a constant current of 2.5A. a) find the energy that it holds b) what is its voltage c) what is its energy after its current drops to zero and stays zero What power is dissipated when a 20 olhm resistor is connected to it
A typical method of measuring the linearity of an amplifier is called the "Two-tone" test. Signals at f1 and f2 are input to the amplifier and the output spectrum is observed. Assuming that signals at 14.1 and 14.2 MHz are input to an amplifier.
1. The closed-loop transfer function of a system is T(s) = 11.1(s +18)/ ((s + 20)(s2 + 4s +10)) Plot the poles and zeros of this system and discuss the dominance of the complex poles. What overshoot for a step input do you expect
