EEL 4930 Audio Engineering HW#9 Due #20 (Wed. 5/7/10) #19A 1. Draw the schematic of an op-amp circuit to convert left (L) and right (R) signals to (mid) M =
L + R and (side) S = L — R form. Select some reasonable resistor values. 2. Analyze this circuit and plot its frequency response (magnitude in dB vs. frequency on log
scale) for three conditions: (a) R1=R2 = 55 k9
(b) R1: 10 1<§2;R2 = 100 kg
(0) R1: 100 k9; R2 = 10 k9 What audio function does this control implement? ...
