Periodic impulse train train

hi, how can i generate a periodic impulse train with each impulse having a unit amplitude and 1 sample in width with a sampling frequency fs and 1second in length. thank u very much in advance

Answer 1

[Fangjun Jiang]

f=10; %frequency of the impulse in Hz
fs=f*10; % sample frequency is 10 times higher
t=0:1/fs:1; % time vector
y=zeros(size(t));
y(1:fs/f:end)=1;
plot(t,y);

I want to define impulse train from -1 to 1.Please correct my code.

f=1/T;           %frequency of the impulse in Hz
fs=f*2*pi;            % sample frequency is 10 times higher
t1=0:1/fs:1    % time vector
t2 = 0: -1/fs:-1
t=[t1 t2]'
y=zeros(size(t));
y(1:fs/f:end)=1
plot(t,y);

[Fangjun Jiang]

f=1/T;           %frequency of the impulse in Hz
fs=f*10;            % sample frequency is 10 times higher
t=-1:1/fs:1    % time vector
y=zeros(size(t));
y(1:fs/f:end)=1
plot(t,y);

Answer 2

[mohit sharma]

f=1/T; %frequency of the impulse in Hz

fs=f*2*pi; % sample frequency is 10 times higher

t1=0:1/fs:1 % time vector

t2 = 0: -1/fs:-1

t=[t1 t2]'

y=zeros(size(t));

y(1:fs/f:end)=1

plot(t,y);

%% Here impulse train or dirac comb function

%% Creating a impulse train

f=10;% frequency of impulse

fs=4*f;% sampling frequency with oversampling factor

Ts=1/fs;% sampling interval or period

t=-25:Ts:25;% Time range for impulse train

% creating impulse function

x=@(t) (t==0)

%% Method 1

xshift = x(t)+x(t-1)+ x(t+1)+x(t-2)+x(t+2);

subplot(311)

stem(t,xshift,'^','linewidth',2);grid on;ylim([0 2]);

xlabel('Time(sec)');ylabel('Amplitude');

title('shifted impulse with origin');

%% Method 2

xshift = @(t) x(t)+ x(t-1)+x(t+1)+x(t-2)+x(t+2)

subplot(312)

stem(t,xshift(t),'r','^','linewidth',2);grid on;

xlabel('Time(sec)');ylabel('Amplitude');

title(' Using Annonimous function');ylim([0 2]);

%% impulse train

sum=zeros(size(t))

for k = -25:25

sum = sum+x(t-k)

end

subplot(313)

stem(t,sum,'^','linewidth',2);grid on;xlabel('Time(sec)');

ylabel('Amplitude');

title('Impulse Train ');ylim([0 2]);

%% completed

%% Output:
