AND / OR Gates – Video Tutorial

This is a video tutorial of AND/OR gate. This video explains how the AND gate and OR gate works. AND gate has two input and one output. the rule of AND gate is when both input are “1”, the output is 1(on). The OR gate also has two input and one output but its rule is different from AND gate. […]

Operational Amplifier (Op-Amp) Oscillator

This is Operational an Amplifier (Op-Amp) Oscillator circuit. This circuit has some advantages, they are this circuit can be operated at low frequencies with relatively small capacitors, it has a completely-symmetrical output waveform along with a buffered output and it will always self start and cannot hang up because there is less dc positive feedback than negative feedback. Returning R2 […]
