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, ...

Using a PWM as Digital-to-Analog Converter

Several microcontroller applications utilize a digital-to-analog converter. Though many of these applications require a complex DAC, some may only need a simple single-channel DAC. Because most MCUs ...

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 ...

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 ...
