An op-amp has a single-pole, open loop response with the dc open loop gain of A0=20,000 and the pole frequency at fp=40 Hz.
A. If this amplifier is connected as a non-inverting amplifier configuration with the closed loop gain of 50, find the frequency at which the loop gain |Aß|=1, find the phase margin.
B. If the above amplifier is wired as a unity gain buffer configuration, what will then be the frequency at which the loop gain |Aß|=1?
Design lowpass IIR filter with the following specifications: Filter order = 2, Butterworth type Cut-off frequency=800 Hz Sampling rate =8000 Hz Design using the bilinear z-transform design method
Once the voltage across the load reaches 5V the load will no longer act as an open circuit and the capacitor will discharge. Once the load voltage has droped to 0.2 the load will act as an open circuit and the capactior will begin to charge once ..
A "ferrite" having a relative permeability of 50 H / m, that operates with flux densities sufficiently small, may be considered a single material. If the magnetic flux density in the material is B = 0.05 T, H and M. halle How to compare the values

PAL12H6 (12 inputs, 6 outputs, AND-OR structure, two output OR's have 4 AND gate inputs and four output OR's have 2 AND gate inputs). NOTE: you need to show only appropriate product terms used for PAL implementation
R3 connects to point N in the center with current going upward and R1 is to the left of this at the top and then it down to V1, with the current going from R1 to V1. To the right you have R2 across from point N and then V2 is down from this. The c..
