First-order Butterworth Active Low-pass Filter

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 ...

Active Low Pass Filter Bode Plot Analysis using Siglent SDS2102X Plus Oscilloscope

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 ...

Getting An RF Low-Pass Filter Right

If you are in any way connected with radio, you will have encountered the low pass filter as a means to remove unwanted harmonics from the output of your transmitters. It’s a network of capacitors and ...

Filter Trims Ultra-Precision Voltage Reference

VOLTAGE REFERENCES generate wideband noise spectrums. For most semiconductor devices, this spectrum usually has a wideband “white noise” component with relatively constant power density versus ...
