This circuit was found in an American documentation from 1970. We can increase the number of multiplier steps to have higher output voltage. The operating frequency is around 1.35 kHz.
In the figure we have a simple way to obtain (almost) sinusoidal signals from an integrated...
This circuit is from a Mallory 1968’s documentation. The integrated circuit is of the time and the...
This circuit is from the 80s. The integrated circuit used is uncommon as is the transducer....
