clc
clear all
n=1:1:5000;%1000 no of data points
fs=1000;%sampling frequency 0f 1000Hz
delt=1/fs;%sampling time interval
f=77;%frequency signal
t=n*delt;%time in seconds
totaltime=1000*delt;%length of time signal
y1=sin(pi*t);%77 Hz sine wave signal
for i = 1:77
if i<2
x=0.001:delt:(1/f);
y2=exp(-x)
else
x=((i-1)/f):delt:(i/f);
y2=exp(-x)
end
end

I didnot go through your code, just read the title of the questions-
i get periodic decaying impulse function using combination of sine and exponential functions
t=0:.01:10;
A=20;
y1=A*sin(30.*t)
%Change ^the value as per requiremnet
y2=-exp(-2*t);
%........^
result=y1.*y2;
plot(t,result);
