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 ...

In this video, I used the bode plot to analyze the low pass active filter’s behavior in practice. There are not many devices that can calculate and demonstrate the bode plot. I used Siglent SDS2102X ...

Linear Technology has introduced a family of five single and dual amplifying active low-pass filters that can drive ADCs. LTC6603 is a dual matched programmable 9th order switched capacitor ...

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 ...

Over the years controversy has raged back and forth on whether brick wall filters used in digital audio (namely for CD playback systems) exhibit phase shifts in the audio band (20Hz to 20kHz). Audio ...

An easy way to conceptualize active filters is thinking about audio speakers. A speaker crossover has a low-pass, high-pass and band-pass effect breaking a signal into three components based upon ...
