This circuit limits the intensity of an audio signal from a control voltage. The circuit is from a 90’s Radio Electronics. The coupler is a type that uses LDR.
The frequency of this oscillator depends on T, which for the audio band can be a common output...
This circuit can work with almost any JFET. The circuit is from an Electronics Now from April...
This voltage-controlled oscillator uses components that are still common in our market. The...
