Using matlab find the frequencies and amplitudes of the fund

Using matlab, find the frequencies and amplitudes of the fundamental and (2nd, 3rd, 4th and 5th) harmonics of a triangular waveform of 100 kHz frequency, amplitude of 5 Vpp, and 0 V offset.

Please show matlab code.

Solution

clc
clear;
disp(\'given triangular wave\');
disp(\'given frequency is 100KHz\');
h=zeros(5,3);
A=5;
disp(\'hormonic || fequency|| amplitude\');
disp(\' number ||    KHz   ||   dBV\');
for i=1:5,
    h(i,1)=i;
    h(i,2)=i*100;
    hv=(4*A)/(i*pi)^2;
    h(i,3)=-20*log(hv);
end
disp(h);

result

given triangular wave
given frequency is 100KHz
hormonic || fequency|| amplitude
number ||    KHz   ||   dBV
    1.0000 100.0000 -14.1255
    2.0000 200.0000   13.6004
    3.0000 300.0000   29.8190
