What is the use of digital filters?
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.
What is digital filter and its types?
There are two fundamental types of digital filters: finite impulse response (FIR) and infinite impulse response (IIR). As the terminology suggests, these classifications refer to the filter's impulse response.
How many types of filters are there in DSP?
There are two types of filters in the digital realm: Finite Impulse Response (FIR) filters and Infinite Impulse Response (IIR) filters. They are very different in essence.
What is a filter in digital design?
• A digital filter is a mathematical algorithm implemented in hardware and/or software that operates on a digital input signal to produce a digital output signal for the purpose of achieving a filtering objective.
