Butterworth filter is a type of filter whose frequency response is flat over the passband region. Low-pass filter (LPF) provides a constant output from DC up to a cutoff frequency f(H) and rejects all ...

Determine the critical frequency of the Sallen-Key low-pass filter in the figure above, and set the value of R1 for an approximate Butterworth response. Source: Floyd, T. (1998). Active Low-Pass ...

Today I am experimenting with a single chip Universal Active Filter, in this case I made a small PCB for the UAF-42 from Texas Instruments. I chose this part in particular as it facilitates setting ...
