This circuit can be used with 3 receivers and is intended for low frequencies (medium wave range). We found it in the September 1995 Electronics Now magazine.
Unlike the CIR4620 circuit, the circuit shown in the figure operates by capacitance. This means...
This circuit is from an old publication of 1972 but can be mounted with BC548 transistors for 12 V...
We found this circuit in an old optoelectronics manual from Texas Instruments. However, more...
