The cut-off frequency of the circuit shown in the figure is 750 Hz, with the components used. The circuit applies to almost any operational amplifier and the power supply must be symmetrical.
This circuit has a frequency range of 30 Hz to 100 kHz with an output signal of 1 Vrms. We found...
In the figure we have a second order filter with very high input impedance, using an operational...
Using the HA2400 this circuit can generate signals of a few megahertz depending on R and C. The...
