Step response from impulse response

Since R2020a

Syntax

S = impulse2step(I,dt)

Description

Create Step Response from Impulse Response

Open Live Script

Load the impulse response column matrix from a file.

load('PulseResponseReflective100ps.mat');

Calculate the step response from the impulse response.

step = impulse2step(impulse,dt);

Plot the step response.

plot(t,step)
xlabel('Time (Seconds)')
ylabel('Volts')
title('Step Response')

Figure contains an axes object. The axes object with title Step Response, xlabel Time (Seconds), ylabel Volts contains 2 objects of type line.

Input Arguments

`I` — Impulse response
column matrix

Input impulse response, specified as a column matrix. The first column contains the primary impulse response and the subsequent columns (if any) contain the crosstalk impulse responses.

Data Types: double

`dt` — Uniform sampling interval
positive real scalar

Uniform timestep of the waveform, specified as a real positive scalar in seconds.

Data Types: double

`S` — Step response
column matrix

Converted step response, returned as a column matrix. The first column contains the primary step response and the subsequent columns (if any) contain the crosstalk step responses.
