Introduction to Pulse Code Modulation (PCM)

Introduction to Pulse Code Modulation (PCM)

PCM converts an analog signal into a bit stream by sampling, quantizing, and encoding. See how a 3-bit quantizer reduces each sample to one of 8 levels.


How Pulse Duration Shapes Distortion and Recovery in Flat-Top PAM

How Pulse Duration Shapes Distortion and Recovery in Flat-Top PAM

The aperture effect rolls off high message frequencies in flat-top PAM. Here’s how pulse duration limits that distortion to under 0.5% and when an equalizer helps.


Introduction to Flat-Top Pulse-Amplitude Modulation

Introduction to Flat-Top Pulse-Amplitude Modulation

Flat-top PAM holds each sample’s amplitude for the pulse duration, weighting the spectrum with a sinc function. Here’s how that weighting leads to the aperture effect.
