range. Bessel low-pass filters, therefore, provide an optimum square-wave transmission behavior. However, the passband gain of a Bessel low-pass filter is not as flat as that of the Butterworth low-pass, and the transition from passband to stopband is by far not as sharp as that of a Tschebyscheff low-pass filter (Figure 16- 9).

The basic configuration for an active low-pass filter using an operational amplifier is as follows: Place the operational amplifier (op-amp) on a breadboard. Connect a resistor (R) between the input signal source and the non-inverting input ( V in ) of the op-amp.

Second-Order Active High-Pass Filter. If we swap the resistor and capacitor in an RC low-pass filter, we convert the circuit into a CR high-pass filter. We can then cascade two CR high-pass filters to create a second-order CRCR high-pass filter. If we incorporate this passive configuration into the Sallen-Key topology, we have the following: In an active low pass filter, the peak of the passband of the filter can be much larger than the input voltage signal because there is amplification. For passive low pass filters to be built, all that is required are resistors and capacitors. Active low pass filters require either transistors or op amps to provide amplification to the circuit.
