Basic review of how the different kinds of analog-to-ditital converters wor, with a sidebar relating them to appropriate applications. ADCs quantize time-varying analog voltages into a sequence of ...

The sources of noise in a signal chain can be either internal or external. Managing noise in the signal chain requires meticulous examination of each circuit in the chain to minimize noise where ...

As much as it’s an analog world, it is often being chopped up into digital pieces. As communications go digital and the computing power increases, signals are being transformed into digital words that ...

As its name implies, the function of an analog-to-digital converter (ADC) is to convert analog signals to digital representations for processing by a microcontroller (MCU), field-programmable gate ...

The market for audio applications and devices has significantly grown over the last couple of years. Applications such as smart speakers, Bluetooth speakers, smartphones, and voice-controlled ...

Researchers from the Institute of Science Tokyo and Canon ANELVA Corporation built an ultrathin ferroelectric memory ...

A signal-to-noise ratio (SNR) lets us express the relationship between signal and noise powers, as well as between the root-mean-square (rms) values of signal and noise voltages: SNR (dB) = ...

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 ...

It’s tough to find a project these days that doesn’t use an analog-to-digital converter (ADC) or digital-to-analog converter (DAC) for something. Whether these converters come as built-in peripherals ...
