How to generate this spike?(Spike only. Not the sine wave). It should be generated with an exponential decaying sinusoid. The frequency of sinusoid is 10^7 Hz. If not possible to generate using exp. function, please suggenst other idea.

hello
try this code ; I guessed the pattern period about 0.01 second but you can of course modify it
Fs = 1e7;
dt = 1/Fs;
one_signal_period = 0.01;
t=(0:dt:one_signal_period-dt); % remove one sample at the end ( dt) to avoid duplicate with next segment first point
a= 5*exp(-t/0.0007);
a(1) = 0;
b=1*exp(-t/0.0007);
b=flip(b);
y = a+b;
figure(1)
plot(t,y,'b');
% create repetitions of the signal
rep = 5; % repetitions
y_rep = [];
for k = 1:rep
y_rep = [y_rep y*(-1)^k];
end
t_rep = (0:numel(y_rep)-1)*dt;
figure(2)
plot(t_rep,y_rep,'b');
