% ECE301 Fall 2008
% Homework #1
clear;
clc;
% Part A
% Define frequencies
% All frequencies found using equations from HW sheet
B = 495;
A = 440;
G = 396;
F = 352;
E = 330;
D = 297;
C = 264;
% Define note durations
% Assuming bpm=135
% Quarter note
Qn = 60/135;
% Eighth note
En = Qn/2;
% Half note
Hn = Qn *2;
% Whole note
Wn = Qn *4;
% Sample rate
delta = 1/44100;
% Melody
notes = [G, A, B, C, D, E, E, F, F, F, C, D, E];
rhythm = [Hn, Qn, Qn, Qn, En, Qn, Qn, Qn, En, En, Qn, Qn, Hn];
% Regular time
for counter=1:13
t=0:delta:rhythm(counter);
d=sin(2*pi*t*notes(counter));
Sound(d,1/delta);
end
