This circuit generates rectangular signals from 2 Hz to 20 kHz using an operational amplifier. The circuit is from 1984 Radio Electronics. The power supply must be symmetrical.
Depending on the components, given in the table, this circuit can amplify signals of 100 MHz or...
Found in Ferranti's 1969 documentation this circuit has a maximum operating frequency of 7.5 MHz....
An interesting interface solution that can be provided in some cases is the one shown in the...
