Software: The Ramanujan Filter BankThis page contains Matlab implementation of the Ramanujan Filter Bank (RFB), introduced in [7] and [10]. The RFB filters have integer coefficients, and directly produce time vs period plots for signals whose periodic nature changes with time. This includes signals that are periodic only for a short duration and signals such as chirps. Matlab code for the RFBClick here to download the Matlab code. Please read the README_RFB.txt file for instructions. |
