Hi , please I'm confused with the following time vectors t1 and t2 to generate 0.5 second duration sinusoid signal :
Vector t1 has equally spaced samples at Ts intervals , but the signal x1 has duration equal to ( duration+Ts ) seconds , I checked x1 length .
Vector t2 has equally spaced samples not Ts intervals , signal x2 dutaion = ( duration ) secons excatly , which time vector is correct ?
%% Generates a sine wave of 0.5 second duration
F0=10; % Sinusoid frequency in Hz
Fs=200; % sampling frequency samples / sec
duration=0.5; % signal duration is seconds
Ts=1/Fs; % sampling Interval
t1=0:Ts:duration; % time vector with equally spaced samples at Ts intervals
t2=linspace(0,duration,duration*Fs); % time vector with samples not at Ts intervals
x1=sin(2*pi*F0*t1); % signal duration = ( duration+Ts ) seconds , length = 101 points
x2=sin(2*pi*F0*t2); % signal duration = ( duration ) secons , length = 100 points
