firStudio

firStudio is a versatile tool for the design of Finite Imp[ulse Response (FIR) filters based on windowing methods and the equiripple Park-McClellan method.

Features:

Design of an FIR filter based on the windowed method (using rectangular, Hamming, Hanning, triangular, Kaiser-Bessel, Dolph-Chebychev and Blackman-Harris window functions) and the equiripple Park-McClellan method.


Filter length can either be specified or estimated based on filter parameters.

Design of low-pass, high-pass, band-pass, band-stop Raised Cosine and Root Raised Cosine filters with the specified roll-off factor.

Plotting the Frequency Response (Magnitude and Phase).

Plotting the Impulse Response.

Saving impulse and frequency responses as images using the .png format.

The graphical user interface of firStudio is deliberately designed to be as intuitive as possible.
