The Nyquist plot combines the two Bode plots of gain versus frequency and phase shift versus frequency on a single plot.

Correct Answer: True
Bode plots show the frequency response of a system. There are two Bode plots one for gain (or magnitude) and one for phase. The Nyquist plot combines gain and phase into one plot in the complex plane. It is drawn by plotting the complex gain g(iω) for all frequencies ω. That is, the plot is a curve in the plane parameterized by ω.

Consider the four statements given below about the function f(x) = x4 - x2 in the range $$ - \infty P. The plot of f(x) versus x has two maxima and two minima.
Q. The plot of f(x) versus x cuts the x axis at four points.
R. The plot of f(x) versus x has three extrema.
S. No part of the plot f(x) versus x lies in the fourth quadrant.
Pick the right combination of correct choices from those given below.

Gain margin and phase margin can be determined from Bode plots as well as Nyquist plot.

A big rectangular plot of area 4320 m2 is divided into 3 square-shaped smaller plots by fencing parallel to the smaller side of the plot. However some area of land was still left as a square could not be formed. So, 3 more square-shaped plots were formed by fencing parallel to the longer side of the original plot such that no area of the plot was left surplus. What are the dimensions of the original plot ?

Which concentration plot is linear for a first order reaction? (A is one of the reactant) versus time b) 2 versus time c) Ln versus time d) √ versus time

Assertion (A): The phase angle plot in Bode diagram is not affected by the variation in the gain of the system. Reason(R): The variation in the gain of the system has no effect on the phase margin of the system.

The unit circle of the Nyquist plot transforms into 0dB line of the amplitude plot of the Bode diagram at

In a Wien bridge oscillator, it is found that at the frequency ωO there is no phase shift in RF/R gain loop and the phase shift of the amplifier is also zero. Then what is the equation for the radian frequency, given R1, C1 is the series network of bridge and R2, C2 is the parallel network?
