The use of operational amplifiers as HF filters

Published 16.07.2010

Now let's consider the inclusion of operational amplifiers as filters.
High-pass filter. It is used to cut off the signal of the frequency below a certain threshold, which is also called the "cutoff frequency".
Typical high-pass filter circuit is the following:
The first circuit is a circuit with inclusion of the non-inverting operational amplifier, the second is with an inverting one ...
