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 ...

This isn’t a hack. But it is a decidedly interesting piece of mechanical technology. The Whiffletree shown above is a way to turn binary data into a mechanical analog value. [Bill Hammack] explains ...

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 ...

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 ...

In this week’s video, we continue on where we left off last week with another in our series of videos where we discuss how to program for the ATmega328p processor. This week, [Jack] takes a look at ...

Devices that support S-Video and stable drivers, such as the Diamond VC500, can yield stronger results when paired with a ...

Photonic analog-to-digital conversion (ADC) represents a paradigm shift in signal processing by leveraging the inherent advantages of photonic devices to digitise analog signals. The approach aims to ...

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 ...

Every sound you hear in real life is analog, but digital recording converts the original sound into a sequence of numbers. No wonder analog and digital sound so different! Ex-movie theater ...

The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...
