An optocoupler is a combination of a light source and a photosensitive detector. In the optocoupler, or photon coupled pair, the coupling is achieved by light being generated on one side of a ...

This simple scheme is based on the circuit shown below (Figure 1) in my recent article [1]. Figure 1 Using common transistor optocoupler to achieve a tube-like sound. It is known that the main feature ...

Relays usually are driven using optocouplers, which offer isolation between analog and digital grounds to ensure that switching currents in the relay coils do not affect the noise margin of the ...
