A technique that is used to sample voice waves and convert them into digital code. Delta modulation typically samples the wave 32,000 times per second, but generates only one bit per sample. See PCM.

One popular way to reconstruct analog signals in microcontrollers (µCs) is through pulse width modulation (PWM). However, this modulation produces a large number of harmonic components, which limits ...

In the process of debugging and validating both digital and RF designs, the oscilloscope Fast Fourier Transform (FFT) function and a variety of other math functions can prove valuable to designers ...
