vco
Voltage Controlled Oscillator
Calling Sequence
y=vco(x,fc,fs)
y=vco(x,[fmin fmax],fs)
Parameters
Description
y=vco(x,fc,fs)
Creates a frequency modulated cosine wave y whose frequency varies as the magnitude of x
x lies in [-1,1]. x=-1 corresponds to a frequency of 0, x=0 corresponds to a frequency of fc
and x=1 corresponds to a frequency of 2fc.
y=vco(x,[fmin fmax],fs)
Scales the frequency range so that x=-1 corresponds to a frequency of fmin and
x=1 corresponds to a frequency of fmax
If x is a matrix the same operation is performed on the columns on x
Size of y is the same as the size of x
Example
x=rand()
x =
0.2113249
y=vco(x,2000,8000)
y =
0.9454092
