After the fm antenna amplifier circuit is constructed, the power supply should be connected to it. You must then test the DC voltage in the cable. This must be between 15.5 and 36.6 volts. Then test ...

IC2 is a good quality operational amplifier (200 V/us) that acts like a buffer between Schmitt input and output. The triangle wave generator circuit can generate signals with frequencies up to 300 kHz ...

The circuit is designed for high analogue signal fidelity (as is, it would need the pulses to be generated with an DAC delivering a signal with appropriate upper and lower signal levels), but dipping ...

This simple, robust, and low-cost signal generator, based on the LM386 power amplifier IC, provides a trio of audio-band signals with three different simultaneous outputs at the same frequency ...

Instead, they should have an adjustable top value and a separately adjustable bottom value: 5V and 0V, for example. The other day, I thought of a way to modify a conventional ‘diamond buffer’ (circuit ...
