The AudioFile: Analog-to-digital conversion

In previous installments of the AudioFile, we've talked about basic PCM audio, which encodes audio into a series of numbers that a computer can play or manipulate. We've also discussed the process of ...

Analog-to-digital converter

Analog-to-digital converters, or ADCs, are somewhat monolithic devices for most users, a black box that you ask nicely for the value on its input, and receive a number in return. For most readers, ...

Do modern AV receivers convert digital inputs to analog (apart from the speakers)?

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 ...

Convert analog signals to an industry standard Modbus output

A great many industrial sensors — flow, level, temperature, pressure, pH, and the list goes on — produce a 4-20 mA output, but today's factories increasingly need digital inputs via standard field ...

Digital-to-Analog Converter

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 ...
