Basic pulse generator using op amp IC-4558
This is a sample pulse generator using op amp. We often use 555 timer to build a simple pulse generator. The op amp is also easy in oscillator form. More! Read more
Simple function generator using op amp LM1458
This is function generator using op amp. As usual the function generator will be expensive and difficult.However, this is a simple circuit with only two ICs.This circuit is suitable for experiments. The output is 3 waveform , Square wave signal amplitude 7Vp-p, Triangular wave = 2Vp-vp and sine wave = 2Vp-p all have the frequency … Read more
