Figure 2 A circuit with an optocoupler (TLP621) which generates higher (even) harmonics that can be added to the original signal to achieve a tube-like sound. Transistor Q1 creates a current through ...

And while simple on-off control of a device through an optocoupler ... circuit is required, there’s one more missing ingredient: the amount of light the LED puts out per milliamp of input ...

Fig. 1 shows a diagram of a motor-drive circuit between a microcontroller unit (MCU) and an IPM. Seven units of digital optocoupler ACPL-W456 isolate the IPM's seven gate driver inputs ...
