In this oscillator circuit using 3 TTL inverters we have all the conditions for the frequency calculation. Power must be supplied with 5 V. The circuit is from an American TTL documentation.
The purpose of this circuit is to convert a rectangular pulse into a sharp pulse for triggering an SCR. The...
In reality what we have is a microphone amplifier that works with 4 batteries and a magnetic...
) These two circuits were obtained in a 1977 Radio Handbook. The transistors are from that time,...
