A digital sampling oscilloscope obtained the following eye diagram while observing the characteristics of a 1-Gbps digital signal. Histograms were obtain using the built-in function of the scope at a sampling instant midway between transitions (i.e., at the maximum point of eye opening). Detailed analysis revealed that each histogram is Gaussian. One histogram has a mean value of 2.8 V and a standard deviation of 150 mV. The other has a mean of 120 mV and a standard deviation of 75 mV. Estimate the BER level when the threshold level is set at 2.0 V
A (3V, 300mA) flashlight bulb is to be used as the dial light in a 120V radio. What is the resistance of the resistor that should be connected in series with the flashlight bulb to limit the current
Estimate the LSB step size of the DAC described in Exercise 6.7 using its measured full-scale range (i.e. using the endpoint method). What are the gain error and offset error?
How is a frame relay address field extended (based on the ANSI standard)? Explain how it works.
Determine the transfer function for a first order low pass filter with a cutoff frequency of 1000 radians/sec (note radians and not Hertz) and a pass band gain of 1 using the following types.(a) Butterworth type(b) Chebyschev type
determine the series resistance needed to convert a galvanometer to a voltmeter reading 15V on full scale deflection if a current of2.5mA causes full scale deflection and the resistance of the coilis 10
What is the minimum required kVA rating of each transformer?
A 60-watt outdoor lightbulb is advertised as having an average life (i.e. MTTF) of 1,000 operating hours. However, experience has shown that it will also fail on demand an average of once every 120 cycles.
Design a 16 bit adder using both the ripple carry and CLA methods. Use 4-bit CLA blocks for the carry-lookahead design. Use only two-input logic gates in your design. Simulate the design using LogiSim at the logic gate level.
Determine the first and second law efficiencies for heating a liquid from temperature T to temperature T + ΔT in a closed, uninsulated tank.
An amplifier has an input signal, VIn = 250 V. The output voltage, VOut = 30 mV. What is the gain in dB for the amplifier at that frequency
A CT has a current ratio of 100/1. If the primary load current is 100 A, determine the excitation current, the maximum ratio error and the maximum phase angle error if the burden is 5 ohms. The CT characteristic gives an excitation current of 0.01..
