### Channel Impulse Response of Visible Light Communication link

I'm doing research into Channel Impulse Response of VLC links for my MSc degree thesis and I have encountered a lot of troubles when doing experimental work and processing the data. For context, the ...

### Why use white noise over an impulse signal (or vice versa) to understand how a system would behave?

An impulse signal and white noise both have a flat spectrum. When they are passed into a system, the response will indicate how each frequency component will be modified by the system. Is there any ...

### Does the root mean square (RMS) value of the impulse response function (IRF) mean for something？

Considering a single-input, multiple-output linear system, I have the impulse response function between the input point and each output point. If I calculate the RMS of each impulse response function, ...

### Convolution with impulse response of damped harmonic oscillator acceleration

To get the way of the mass of a driven damped mass spring system I can convolve the impulse response $g(t)$ of the system with a driving force: $x(t) = F(t) * g(t)$ This works for me in python using ...

### Show that the impulse response of an LTI system can be determined by observing the output and inputting white noise

Problem Show that the impulse response of an LTI system can be determined by observing the output and inputting white noise. Attempt Let $x(t)$ be the input signal (white noise) and $y(t)$ be the ...

### Decay of the impulse response for poles contained in the unit circle

I've been struggling with the following exercise in Ljung's "System Identification: Theory for the User" (Problem 3G.1): Given a rational transfer function $G(z)$ such that its poles are all ...

### Linear-phase zero-latency IR?

Is it possible to capture an Impulse Response of a linear-phase EQ (talking music software here) and then apply it to a new signal in a way that is both zero latency and phase-accurate? My idea was to ...

### How to find response of DT system to an input

This year I have fallen behind in my Signals module due to poor mental health and insomnia. I have a homework due in 9 hours and dont understand anything, while also not having the time to learn ...

### Impulse response of a discrete time cascading system

My lecturer has decided that in order to pass our signal analysis class, we have to give a presentation on the blackboard in front of the entire class, so its kinda critical that i get this right. (...

Suppose we have a linear linearly time varying system $S$ such that the output depends on the input + the time at which the system becomes excited so $S(t,t_{0}) \rightarrow g(t_{0})S(t)$ and it is ...
