suggestions on generating periodic decaying exponential signal

2 views (last 30 days)
Hi, i am trying to generate a periodic decaying exponential signal in the time interval between -5 and 100 . I am trying to visualize it like a sawtooth waveform (but reversed and having gradual decay). can someone help me with this
t=-5:t_step:100;
bt_new=0;
L=0.018;
t_step=0.1221;
N= L/t_step;
for l=0:2.0930e-03:N
bt = exp(-0.24*((t-(l.*ones(size(t))*t_step))));
bt_new =bt_new+bt;
end
plot (t,bt_new);
I am trying to generate a periodic decaying exponential, any ideas

is this close to what you want?
clear;clc
t = -5:.1:100;
plot(t,fliplr(sawtooth(t)).*exp(-t./20))

Thanks for the response. the answer is close to what i expected. But basically i want an periodically decaying exponential signal (whose amplitude varies between 1 and 0).
but while using a sawtooth waveform the amplitude extends from -1 to 1. I want to manipulate the amplitude. Do you have any suggestions
