How to interpret the amplitude of impulse() results
Hi,
For the given transfer function, the frequency response and step response make sense to me.
But why the amplitude of impulse response is so large?
If I want to use the impulse response to conv any input signals to the system, the amplitude of output will be wrong.
SInce the Delta function doesn’t exist in reality, how does Matlab impulse() function compute it? Do I need to scale it?
Thanks in advance!

fco = 0.7e9;
wco = fco * 2 * pi;
tau = 1 / wco;
num = [1];
den = [1/wco, 1];
% check tf model

sys = tf(num, den)
