What Does FIRF Stand For?

FIRF stands for Finite Impulse Response Filter

FIRF, or Finite Impulse Response Filter, is a type of digital filter characterized by a finite number of coefficients, which defines its response to an input signal. FIR filters are widely used in signal processing due to their inherent stability and linear phase response. They process input data through convolution with a fixed set of filter coefficients, producing an output that accurately reflects specific frequency characteristics while minimizing distortion. FIR filters are commonly employed in various applications, including audio processing, communications, and control systems.
