| **convolutioncalculatorv1.0.zip** | 516k | 11-01-09 | | **Convolution Calculator** In introductory digital signal processing courses, the convolution is a rather important concept and is an operation involving two functions. The word “convolve” means to wrap around. In essence, the convolution of two functions is “sweeping” a function across another function and multiplying their overlapping regions. One function is kept stationary while one function is flipped across the y axis and is then shifted left or right. The amount of shifting depends on the value of n. Since we are dealing with discrete values, we multiply the functions and sum the products to compute the convolution at that point of n. The purpose of this program is to take a set of values for x[n] and a set of values for h[n] and compute their convolution, x[n]*h[n], which results in the output, y[n]. The values of x[n] and y[n] must be discrete and cannot rely upon a formula. In example, the program cannot take an equation in terms of n and compute the convolution that way. You must enter individual values. It is also assumed that the system is LTI/LSI (Linear Time/Shift Invariant). |

'Room Cavity Ratio' is used to look up the 'Coefficient of Utilization' in a fixture catalog, 'Lamps Required' calculates how many lamps are needed to generate the target footcandles, 'Lamps to Footcandles' is used when you realize that you cannot fit the exact 'Lamps Required' into the room and want to know how close your adjusted lamp number is to the target footcandles (should I add or subtract a fixture?), and 'Total Fixture Watts' tells you the total draw of all of your fixtures combined. The program is self-explanatory, and does not contain any notes or display any formulas. Requires 1838 of calculator memory. If you want notes and visible formulas, and do not mind a larger memory footprint, then use Light6N which requires 4238. Students are encouraged to use Light6N. Free software. Use at your own risk.

| **timecons.zip** | 1k | 03-05-07 | | **Time Constants** Any person deep into the electrinics field would really like this one. I was having a little trouble dealing with the charge and dischargeing of capacitors and coils (Time Constants) so I created this program to assist me during test time. I haven't found anything wrong with it, just some minor bugs like not clearing the graph when you exit the program. I could have fixed it but it didn't really bother me. Anyone is more than welcome to toy with it, its pretty straight forward to understand. Includes both RC and LR formulas as well as a very handy solver utility. Also it includes the Universal Graph as well as a table that gives you the percentages of each constant. Be sure you adjust your "tblset" before running the program to like 1 count.
