Ladies, Gentlemen,
Please let me say you that following code when is executed in MATLAB online R2020b its resaults have excellent accuracy. Is it possible retain its accuracy when is executed in dsp kit?
SampFreq = 16000;
Segm = 1:1600;
%% Generates signal
FirstHarmFreq = 101;
FirstHarmAngles = FirstHarmFreq*2*pi/SampFreq*Segm+(1.9*pi);
SinFirstHarmAngles = sin(FirstHarmAngles);
SecondHarmAngles = FirstHarmFreq*2*2*pi/SampFreq*Segm+(0.9*pi);
SinSecondHarmAngles = sin(SecondHarmAngles);
ThirdHarmAngles = FirstHarmFreq*3*2*pi/SampFreq*Segm+(0.3*pi);
SinThirdHarmAngles = sin(ThirdHarmAngles);
Xn = SinFirstHarmAngles+SinSecondHarmAngles+SinThirdHarmAngles;
%% DFT Grid
fftFirstHarm = 110;
LowerLimit = fftFirstHarm-10;
UpperLimit = fftFirstHarm+10;
TestFreqs = LowerLimit:0.1:UpperLimit;
TestPowerSpectrum = ones(1,201);
for m = 1:201
TestAngles = TestFreqs(m)*2*pi/SampFreq*Segm;
XnCos = sum(Xn.*cos(TestAngles));
XnSin = sum(Xn.*-sin(TestAngles));
TestPowerSpectrum(m) = XnCos.^2+XnSin.^2;
end
[maxPowerSpectrum, testFreqIndex] = max(TestPowerSpectrum);
fundFreq = TestFreqs(testFreqIndex);
disp(fundFreq);
