An old algebra teacher used to say, “You have to take what you know and use it to get what you don’t know.” You might say the same thing about converting analog signals into digital. Computers know ...

In the Op Amp circuit shown in the figure, let Rf = 10kΩ, R1 = 10kΩ, R2 = 20kΩ, R3 = 40kΩ, and R4 = 80kΩ. Obtain the analog output for binary inputs [0000], [0001], [0010], . . . , [1111]. Using this ...

Here's why I'm asking: I have a Denon AVR 3803 receiver. I like it quite a bit, except for one glaring (IMHO) omission; in order to use my Sennheiser wireless headphones, I have to run both analog and ...
