This audio noise filter circuit is a bandpass filter for audio frequency band. It filters unwanted signals that are lower or higher than the audio frequencies. It has 2 filters: a low pass filter and ...

Figure 38 A voltage controlled MOSFET band pass filter with linearized drain to source resistance. The bias voltage and Wah-Wah signal, Vww, will need to be doubled in range because of the voltage ...

Most hobbyists use crystals as an external clock signal for a microcontroller. A less common use would be to make a bandpass filter (BPF) for an RF signal. [Dan Watson] explains his crystal ladder … ...

This circuit provides a wideband bandpass filter optimized for FRS applications, with a 10:1 ratio in its corner frequencies. The corner of the reconstruction filter and the anti-aliasing filter ...
