Nyquist stability criterion states that N=Z-P. In this Z denotes Number of stable closed loop poles None of the Choices Number of encirclements of the point (-1, j1) of the Nyquist plot of G(s)H(s) Number of stable closed loop zeros

Styles 1. The noise produced by a resistor is to be amplified by a noiseless amplifier having a voltage gain of 75 and a bandwidth of 100 kHz. A sensitive meter at the output reads 240 μV rms. Assuming operation at 37° C, calculate the resistance of the resistor. If the bandwidth were cut to 25 kHz, determine the expected output meter reading. (Ctrl) -

Consider each of the following four types of oscillations: A. underdamped B. critically damped C. overdamped D. simple harmonic motion Identify the stability and type of critical point (0,0) that represents each type of oscillation and match it the relevant dynamical phase portrait(s) below.
