I need help in MATLAB. I'm working on a circuits lab report and I want to plot the derivative of an input signal. The circuit is a differentiator OpAmp. It is receiving a triangle wave as an input and should output a square wave. (I've included my existing code.) The output formula is: Vout = -(Rf)*C*(dVin/dt) Where Rf is feedback resistance: Rf = 1*10^6; and C = 1*10^-6. EXISTING CODE: %% This section is copied, and then modified from another...

1. In the lab we analyzed filtering 60 Hz power-line noise from ECG signal using a digital (signal processing) filter. Now let's try to an analog (circuit) filter approach to remove the 60 Hz line-noise. Following is an active twin-T notch filter with transfer function: (1+m)((2joRC? +1 Z(a) 2R 2R Here m is the ratio of the two feedback 2C R resistance which determines the gain and...
