a) Design a two-stage signal processoras a distortion box for and electric guitar. The first stage applies a variable gain magnitude in the range 13.3 to 23.3 while the second has a gain of 1/13.3. The distortion effect relies on intentionally driving the first stage amplifier into saturation when its gain is above 13.3. Use a 10 kOHM potentiometer and resistor with value between 1kohm and 100kohm
b) derive a general formula for percent clipping of a unit amplitude sinusoidal test signal; this is the percent of time during one period in which the signal is clipped. The formula includes peak sinusoidal voltage Vp that would appear at the ouput of the first stage amplifier with saturation ignored and actual maximul due to saturation Vs.
