Zener Diode and Series Resistance
In the zener diode circuit calculate the value of the current through the zener diode if the power supply is rated 24 volts at 500 milli amperes. The load voltage is 12 volts and draws a current of 300 milli amperes. Also calculate the value of the series resistance R.
Consider a coffee counter with a single server at which tired students arrive according to a Poisson process. Let the mean arrival rate be two students per ten minutes and assume the serving time is exponentially distributed with an average of 180..
Explain the operation of sequential logic devices and evaluate the output waveform in relation to the clock for QA, QB and QC in the subsequent circuit and show the binary sequence represented by these waveforms
(Combinational versus Sequential Circuits) Which of the fol¬lowing contain circuits that are likely to be combinational and which contain sequential circuits? Explain your rationale.
General questions for network communications, A user message is split into 15 frames, each of which has an 80% chance of arriving error-free. If no error control is used by the data link layer, how many times must the message be sent on the averag..
Calculate the approximate quantization S/N ratio in the baseband audio signal at the receiver output (after the DAC and LPF).
Sketch a block diagram of the arrangement and calculate suitable values of pad resistance if both the amplifier and the line have a characteristic impedance of 600 Ohm.
The voltage and current in the Laplace domain for a certain system is given by V (s) = 1/12 1/s^2 +3, I(s) = s/s^2+3. Is this system best described as resistive, capacitive, or inductive?
Assessment on Electricity and Circuit Theory, What part of a cable are insulators and conductors? Describe, in terms of charged particles, why some objects are electrically attracted to each other, while others repel each other?
A square wave signal with voltage levels 0 volts and 2.0 volt at a frequency of 1.00 MHz is multiplied by a sine wave at a frequency of 5.0 MHz
Define Design with Multiplexer, Design a circuit using one 16 TO 1 multiplexer with W, X,Y,Z on the control inputs
Spectrum Analyzer, A spectrum analyzer is connected to an unknown signal. The spectrum analyzer displays the power level of signals in dBm vertically and frequency horizontally. The spectrum of the unknown signal creates the following display:
Improve the controller designed in part by introducing a mechanism for the disturbance compensation at the plant input. Illustrate advantage of the improved controller by applying the fast varying piecewise constant reference input vector and sinu..
