In the figure we have a simple way to produce tone in a piezoelectric transducer. The frequency depends on the capacitors and the supply can be done with voltages from 1.5 to 6 V.
This circuit is from a 1978 optoelectronics manual from Texas Instruments. The transistor can be a...
This inverter can reach a power of 300 W depending on the transformer used. In this case, a...
This circuit uses an LM3900 transconductance operational amplifier to generate pulses whose...
