Detailed Description

Construct array of pwr objects from a numeric signal.

This is a utility function to help in constructing signal_interface objects that have waveform-defined power scaling.

Example

Generate a dummy waveform with a specified peak-peak voltage
vpp = 4;
testsig = randn(100, 2);
testsig(testsig>0) = vpp/2;
testsig(testsig<0) = -vpp/2;
testsig(:,2) = testsig(:,2)*0.5;

%Use function
[PCol] = getPColFromNumeric_v1(testsig, [10, 30].');

%Construct signal_interface object using waveform and new PCol
sigparams.Fs = 1;
sigparams.Rs = 1;
sigparams.Fc = 0;
sigparams.PCol = PCol;
test_signal = signal_interface(testsig, sigparams);

%Check performance
preim(test_signal)

Function Documentation

function getPColFromNumeric_v1	(	in	waveform,
		in	varargin
	)

Construct array of pwr objects from a numeric signal.

This is a utility function to help in constructing signal_interface objects that have waveform-defined power scaling.

Parameters

waveform	Array of signal waveforms (each column is an independent signal) [unit].
SNR	Signal-to-noise ratio of output pwr object. Can be passed as an array or scalar value [dB]. [Default: inf]

Return values

PCol	Array of pwr objects with power set from raw waveform
