Many digital systems use filters to remove noise, provide spectral shaping, or perform signal detection. Two types of common filters that provide these functions are Infinite Impulse Response (IIR) ...
An active filter can be expected to provide amplification along with band limiting to eliminate components in the signal path. Though the use of oversampling audio converters has significantly ...
The second-order multipurpose filter described here can perform as a low-pass, bandpass, high-pass, or notch filter at audio frequencies. What makes this filter unique is that all of its ...
