Question

The summing amplifier can be used as a digitally
controlled volume control using the circuit shown
. The individual bits of the 4-bit binary
input word (b1b2b3b4) are used to control the position
of the switches with the resistor connected to 0
V if bi = 0 and connected to the input signal vI if
bi = 1. (a) What is the output voltage vO with the
data input 0110 if vI = 2 sin 4000πt V? (b) Suppose
the input changes to 1011. What will be the
newoutput voltage? (c) Make a table giving the output
voltages for all 16 possible input combinations.
