Signal Toolkit - vco

: y = vco (x, fc, fs)

: y = vco (x, [fmin, fmax], fs)

Creates a signal that oscillates at a frequency determined by input x with a sampling frequency fs.

Inputs:

• x - input data with a range of -1 to 1. A value of -1 means no output, 0 cuoreesponds to fc, and 1 corresponds to 2*fc.
• fc - Carrier frequency
• fs - Sampling rate
• fmin, fmax - Frequency modulation range limits.

Outputs:

• y - output signal
