i want to do simulation to plot this equation;

where i want to change the phi with 0, π/4, and π/2.

Next, I want to do,

where i want to see what is the shape of the graph with multiple tau is used.

Can anyone help me some idea how to start? i appreciate it so much!

What are τ 1 and τ 2 ? Are they numbers?

Hafizah Halip 2019-10-9

yes.

lets say

T1= 2ns

T2 =4ns

you can try something like this

syms tau t
f = exp(-t/tau).*cos(t+1)
func = int(f,t,0,1)
x = 0.01:.01:10;
y = subs(func, x)
plot(x,y)
