PSG
,The Programmable Sound Generator (PSG) is a sound chip designed by General Instrument (GI) in 1978. The specific model used in the CPC is the AY-3-8912 chip.
The PSG is quite primitive. It is able to output a square wave and/or white noise in three separate sound channels (named Channel A, B and C). Each channel can be Some other 8-bit systems used to output tones more sophisticated soundchips such as the [https://youtu.be/7pONRbIHT_w C64 SID], the [https://youtu.be/BANwL2sQ0DM NES APU] andthe [https:/or white noise/youtu.be/-mdjiWBYIqU Gameboy soundchip].
