>> help timeidx TIMEIDX returns numeric index given time string. D = TIMEIDX(T) returns index value in relative days which is suitable for DATENUM math. To work in hours multiply by 24, for seconds multiply by 24*3600, etc. T can be a time string (DD:HH:MM:SS) where DD, HH and MM are incrementally optional and SS can include a decimal fraction.

This script simulates the Binary Frequency Shift keying. Since BFSK is a digital modulation scheme, you can modulate as many bits as you want. however, I have only simulated it for few bits, so that the results are visible. This is code for BFSK only, means it can only modulated two digital states on two frequencies.

This method, known as swept-sine, log-chirp, swept-tone, or sine sweep uses an increasing frequency sinusoid to stimulate an acoustic device under test. The response is processed to compress the response to an impulse response. This method is robust against noise, time variance, and weak nonlinearities.

EDFT (Extended Discrete Fourier Transform) algorithm produces N-point DFT of sequence X where N is greater than the length of input data. Unlike the Fast Fourier Transform (FFT), where unknown readings outside of X are zero-padded, the EDFT algorithm for calculation of the DFT using only available data and the extended frequency set (therefore, named 'Extended DFT').
