Class T Digital Audio Amplifier Technology Overview
... The audio quality of Class-D PWM amplifiers is inferior because of fundamental problems with the PWM approach. The output transistors are not perfect switches and are not perfectly matched, and this causes distortion. The switching of the transistors causes “ground bounce,” which adds noise. There i ...

Broadcast television systems
Broadcast television systems are encoding or formatting standards for the transmission and reception of terrestrial television signals. There were three main analog television systems in use around the world until late 2010s (expected): NTSC, PAL, and SECAM. Now in digital television (DTV), there are four main systems in use around the world: ATSC, DVB, ISDB and DTMB.
