Use MATLAB to solve Problem 2-40.
Problem 2-40:
Given the forward-path transfer function of unity-feedback control systems, apply the RouthHurwitz criterion to determine the stability of the closed-loop system as a function of K, Determine the value or K that will cause sustained constant-amplitude oscillations in the system. Determine the frequency of oscillation.
A coil of wire having negligible resistance and an inductance of 0.248 henry is connected to a 117-volt 50-cycle source.
Consider a system in which a data transfer over a bus takes 500 ns. Transfer of bus control in either direction, from processor to I/O device or vice versa, takes 250 ns. One of the I/O devices has a data transfer rate of 50 KB/s and employs DMA.
The state of strain at a point of an elastic solid is given in the x-y-z coordinates by:
A uniformly doped silicon pn junction at T = 300 K, with Na = 1018 cm-3, is to be designed such that at a reverse-bias voltage of 10 V, the maximum electric field is limited to εmax =105 V/cm. Determine the maximum doping concentration in the n-regio..
The Fourier transforms of odd and even functions are very important. The reason is that they are computationally simpler than the Fourier transform. Let x(t) = e-ItI and y(t) = e-tu(t) - etu(-t). a. Plot x(t) and y(t), and determine whether they ar..
A signal is quantized using PCM. The maximum signal to quantization noise ratio is 20dB. What is the number of uniform quantization levels needed
A box contains a shipment of N (N>4) computer chips, of which four are defective. Four chips are randomly selected and examined as to wether or not the chips are defective. Describe the sample space for this experiment.
An angle-modulated signal with carrier frequency ωc=2πx106 is described by the equation φEM(t)=10cos(ωct + 0.1sin2000πt). a) Find the power of the modulated signal. b) Find the frequency deviation Δf. c) Find the phase deviation Δφ.
Describe how you would use the voltage follower so the output load voltage (as measured with a scope probe) agrees with the value shown on the function generator front panel independent of load impedance. Describe any compromises or inefficiencies..
Design a Finite State Machine which recognizes the serial pattern 111. Assume serial input is applied to input pin Sin and an output pin labeled Sout is 1 whenever the string is recognized. a) draw a state diagram of your design.
To digitally manipulate information we must encode it using binary numbers. Consider an encoding for playing cards. There are 52 cards in a deck and they are divided
When calculating the bending stress of a rectangular plate, one must use the section modulus about the neutral axis of the plate. This axis is at the center of the plate where there is neither tension nor compression.
