Design and implementation of digital filters for audio signal processing Abstract: An analog active filter do not provide a very sharp cut-off for both higher and lower frequency component, while a digital signal processor (DSP) using digital filter effectively reduces the unwanted higher or lower order frequency components within an audio signal.
How digital filters affect analog audio signal levels

Digital audio processing provides a great amount of flexi-bility to system designers. Multiple filter structures can be cascaded to form equalization (EQ), low-pass, high-pass, shelf, and many other filter combinations with relatively low power consumption and little PCB space. Infinite-impulse-response (IIR) filters can be used to easily simu-
Introduction to Digital Filters
https://www.dspguide.com/ch14.htm
Digital filters are used for two general purposes: (1) separation of signals that have been combined, and (2) restoration of signals that have been distorted in some way. Analog (electronic) filters can be used for these same tasks; however, digital filters can achieve far superior results. The most popular digital filters are described and compared in the next seven …

between analog and digital filters is that instead of calculating resistor, capacitor, and inductor values for an analog filter, coefficient values are calculated for a digital filter. So for the digital filter, numbers replace the physical resistor and capacitor components of the analog filter. These numbers reside in a memory as filter

Wave Digital Filters A Wave Digital Filter (WDF) is a particular kind of digital filter based on physical modeling principles. Unlike most digital filter types, every delay element in a WDF can be interpreted physically as holding the current state of a mass or spring (or capacitor or inductor).

Advantages of using digital filters The following list gives some of the main advantages of digital over analog filters. 1. A digital filter is programmable, i.e. its operation is determined by a program stored in the processor's memory. This means the digital filter can easily be changed without affecting the circuitry (hardware).
