Learn types of rectifier circuit using op-amp. A diodes cannot rectifier ACV lower mV. But 741 rectifiers can help it, in filters, signal measurements, etc.
This is all simple LM741 circuits, it's so useful, LM741's general purpose single OP-AMP. UA741's high performance monolithic OP-AMP on single silicon chip.
These are Tone control circuit using op amp - NE5532 or 4558 IC as low noise, with PCB layout, can adjust sound frequency and tone bass, treble, mid and..
I love to collect a lot of circuits. A filter circuit is important in Electronics. I will show you many ideas of noise hum, high-low frequency and more. Some you will…
