A three-pole feedback amplifier has a loop gain given by
(a) Sketch the Nyquist diagram for β = 0.20.
(b) Determine the value of β that produces a phase margin of 80 degrees.
Each start/stop station contains one NO start pushbutton and one NC stop pushbutton.
A sign on hte door of a room you are abour to enterreads DANGER 10,000 VOLTS. Knowing that your body reistance ispresently 500 kΩ, should you worry about touching any of the equipment i the room
An OFDM system with a passband bandwidth of 10 MHz and carrier frequency of 1 GHz is used in an outdoor environment with a maximum delay spread of 15 microseconds.
Consider a 4 input, 1 output digital system (W,X,Y,Z, and f respectively) . Design a POS circuit with any number of inputs such that f(W,X,Y,Z) = M(0,2,4,9,13) + D(6,14).
How to Prove that Volume of The conductor is Inversely proportional to the squire of Voltage ( Vol = 1/V2). And what is the effect of this relation on Transmission and Distribution System ?
Provide an ideal mixing operation with a 10-kHz local oscillator having an amplitude of 2, and eliminate the undesired component by using a band-pass filter centered at 20kHz. The bandwidth should be sufficient to pass the shifted AM signal.
f(t) = (2+j2)e^(-3jt)+j2e^(-jt)+3-j2e^(jt)+(2-j2)e^(j3t) a) Sketch the exponential fourier spectra b) By inspection of part a sketch the trigonometric Fourier spectra c) Find the compact trigonometric Foreir series
If the use of the passive signconvention is specified, find the: (a) complex voltage that results when the complex current 4e^(j800t) is applied to the series combination of a 1mF capacitor and a 2-ohm resistor.
For the system specified by the following difference equation, compute the first five samples of the response to the input given as x(n) = (0.7)^n u(n). y(n) = 0.5v(n-1) - 0.8y(n-2) + x(n) - 0.4x(n-1)
The circuit in given Figure is the ac equivalent circuit of a series-series feedback amplifier. - Determine the transconductance transfer function Ag f = Io/Vs.
Figure 14.5 illustrates the resampling process for the case when the number of samples and resamples is equal to six;that is,the number of particles after resampling is the same as the number of particles before sampling. Explain how this figure i..
Design a clock that displays seconds from 0 to 30 on the FPGA 7-segment displays, with a reset button that resets the clock value at any time.
