### How to obtain an impulse response from an exponential sine sweep (23kHz/50kHz)

I am currently working on my master thesis and have so far generated a broadband ESS to obtain frequency response and impulse response. To generate the ESS as an excitation signal I use the following ...

### How can I find the impulse responce of this ODE?

$$\frac{𝑑^2𝑦(𝑡)}{𝑑𝑡^2} + 2\frac{𝑑𝑦(𝑡)}{𝑑𝑡}+ 1 = 2𝑥̈(𝑡)$$ a. Write Matlab source code evaluate the impulse response of the system. b. Write Matlab source code to evaluate and plot ...

### Why does convolution give the output of a passing a signal through a filter?

I have a rudimentary understanding of Convolution, the Convolution Theorem and why the output z(t) of an LTI system can be found using the convolution of input signal x(t) and the impulse response h(t)...

### Modeling an Acoustic Reflection from a Wall - a Paradox?

I am trying to simulate the reflection of a sound ray, that goes from a sound source, bounces off a wall, and is received by a microphone. The wall has a an absorption coefficient, and a specular ...

### upsample impulse response

I have a system and I know its impulse response $h$, this impulse response was recorded at $f_s = 48000 \texttt{Hz}$, now I can use Matlab to get the system output to an arbitrary signal ($x$) by ...
