FUNDAMENTAL FREQUENCY SIGNAL – [FFREQS]
Outputs the fundamental frequency of selected signal evaluated at each data points.

CATEGORY
Harmonic Analysis

DESCRIPTION
Outputs the fundamental frequency of selected signal using an interval around each point.

RESULT VARIABLES AND PARAMETERS

Result	Fundamental frequency value at each point of the input signal.
Signal	Input
Num_Cycles	Width factor of the window used to evaluate each fundamentals frequencies. (optional, default=1)
Use_Same_approx_Frequency	Use the same Approx._Frequency for each interval of approximation. If false, use the frequency from the previous interval. (optional, default=true)
Approx_Frequency	Search for fundamental frequency around this value (optional, default=Bloc frequency)

SYNTAX
res=ffreqs(input, num_cycles, use_same_approx_freq, approx_freq)

CHARACTERISTICS
