Filtro de paso banda Butterworth - Butterworth Band Pass Filter - Butterworth BPF

107

01:07:22

Como entrada, 3 sinusoidales a 1, 10 y 20 kHz. El filtro de paso banda es un filtro Butterworth de orden 5, siendo 9kHz el corte inferior y 11kHz el corte superior.

Cuenta con buffers a la salida de los generadores de sinusoidales utilizando amplificadores operacionales y amplificador no inversor a la salida para ajustar Vpp.

I had designed a BPF using 3 LC networks but it only gives a 60dB/dec. roll off. From where did you get this 100dB/dec. roll off circuit?

@fatcat2 From here: https://rf-tools.com/lc-filter/ It is a conventional, shunt first, 5th order Butterworth bandpass filter, lower cutoff freq 9kHz and upper cutoff frequency 11 kHz WITH EXACT component values for testing purposes.

Thank you!!! I wonder how people manually perform the hex-pole chebyshev filter calculations!
