Professor teaching us about convolution

AI Thread Summary
Convolution can be solved without graphing by focusing on the mathematical process of point-by-point multiplication and summation of functions. Understanding how to handle unit step functions is crucial in convolution problems, as they can affect the limits of integration. Using software like MATLAB can streamline the computation process for convolutions. The professor's graphical approach aims to illustrate these steps visually. Mastering the underlying equations is essential for effective problem-solving in convolution.

I'm in class watching my professor teaching us about convolution. However, he keeps doing this by creating graphs and stuff. Is there a method through which I can solve convolution problems without having to draw the graphs?

A more general question is how do I treat unit step functions in a convolution problem?
 
Solve the equations, which is generally a point by point multiplication and summing process. I assume that is what the professor is doing, trying to illustrate the steps.

Or, use MATLAB :)

I don't understand your second question.
 

Thread 'Underwater piezoelectric sensor array receive sensitivity'

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...

Thread 'Following up on the recent thread about Earth Resistance measurements'

I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...

Thread 'Beauty of old electrical and measuring things, etc.'

Even as a kid, I saw beauty in old devices. That made me want to understand how they worked. I had lots of old things that I keep and now reviving. Old things need to work to see the beauty. Here's what I've done so far. Two views of the gadgets shelves and my small work space: Here's a close up look at the meters, gauges and other measuring things: This is what I think of as surface-mount electrical components and wiring. The components are very old and shows how...
