The circuit was designed with the combination of high pass filter and low pass filter to create a notch filter circuit. High Pass Filter – an electronic circuit that allows the passage of high ...

Binary search, a decrease-and-conquer approach, plays an important role in testing today�s low-pass filters. When testing a low-pass filter, generally you have to use an arbitrary waveform generator ...

A filter which attenuates frequencies above its cutoff frequency (which is the point where the signal is 3 dB down). The slope of the filter is the rate of attenuation, i.e. 6, 12 or 24 dB per octave.

In this DI, high school student Tommy Liu modifies a popular low-cost DIY oscilloscope to enhance its input noise rejection and ADC noise with anti-aliasing filtering and IIR filtering. Three ...

The circuit of Figure 1 generates sinusoids down to very low frequencies with distortion in the region of 3% or less, yet has no feedback or gain-stabilizing components because none are needed. It ...

Any pointers to good resources on audio filters for WAV files (particularly low-pass filters) implemented in Java? I've found a goodly amount of resources on DSP and filters, but when it gets to ...
