how to generate continuous tone with below conditions as i only able to create the tone from time 0 to 1. Ho to continuous generate it? Create a 3 second signal containing three tones; Tone 220 Hz for 0 < t < 1 Tone 300 Hz for 1 < t < 2 Tone 440 Hz for 2 < t < 3 using s=sin(2*pi*t) and sampling frequency of 8192 Hz
Fs = 8192;
T = 1/Fs;
t = 0:T:1;
t1=1:T:2;
t2=2:T:3;
y = sin(2*pi*200*t);
hold on;
y = sin(2*pi*300*t1);
hold on;
y = sin(2*pi*440*t2);
hold on;
plot(t,y);
xlabel('t');
ylabel('Amplitude');
Thanks
do you mean this?
Fs = 8192;
T = 1/Fs;
t1 = 0:T:1;
t2=1:T:2;
t3=2:T:3;
y1 = sin(2*pi*200*t);
y2 = sin(2*pi*300*t1);
y3 = sin(2*pi*440*t2);
plot(t1,y1,t2,y2,t3,y3);
xlabel('t');
ylabel('Amplitude');
If so, and you want the data to be in two arrays do the next also
t=horzcat(t1,t2,t3);
y=horzcat(y1,y2,y3);
I am not 100% sure if this is what you want, if not, please correct me
