Biomedical Instrumentation
Finite Impulse Response (FIR) refers to a type of digital filter characterized by a finite number of coefficients, which determines its response to an input signal. These filters are widely used in digital signal processing for their stability and ability to provide linear phase response, making them ideal for various applications in biomedical instrumentation. The output of an FIR filter is computed as the weighted sum of the current and previous input samples, using predetermined coefficients, allowing for effective manipulation of signals in both time and frequency domains.
