A Heat exchange in a thermal storage based on phase change materials
Hello, I want to model a thermal battery based on phase change materials (PCM). It is a plate heat exchanger immersed in a PCM bath. The diagram is given in the attached file. I want to determine the temperature at each moment and from everywhere in the battery. The hypotheses are the...- DianeLR

B Mixing two discrete audio signals
Suppose I have two audiofiles in 16 bit PCM, both recorded on a level that, except for the noise and distortion, is maximally recorded, or that the maximum recording level results in the maximum PCM level. So, the signal is recorded on the maximum level such that there is no clipping. If we...- entropy1

How Do You Solve the PCM System Quantization Problem from Leon Couch's Book?
Homework Statement Hi everyone. I was trying to solve an exercise from the book Leon couch, communication systems, number 3.7 of the 6th edition. This is the statement: In a PCM binary system, the quantisation noise mustn t exceed the percentage value P of the peak power. Show that the...- Domenico94

Discovering a Unique PCM: High Volume Change, Low Heat Storage Capacity
I'm trying to find a Phase Change Material (PCM), but the entire industry is pretty one-minded when it comes to what it should be used for - energy storage. You can see by the wording of the Wikipedia article: https://en.wikipedia.org/wiki/Phase-change_material that they list advantages like...- eknifff

How calculate a single frequency of a multifrequency signal?
I'm just coding a program where I've to calculate the individual frequencies inside an audio file *.wav file. The modulation is pcm and the information I've is a lots of points, like this: http://www.renesas.com/media/support/faqs/faq_results/Q1000000-Q9999999/samp_1.gif To be exact, I've...- Richard_Steele

PCM wax freezing outside solid, inside liquid
A colleague and I want to model how a slab of PCM (wax) solidifies as it cools off. What I have noticed in my experiments is that temperature sensors on the top and bottom of the slab say it should be solid, as they read well below the melting point. But when I peek at the sample, the center...- CraigHyatt
