Attenuation

A still atmosphere attenuates sound as a function of frequency, temperature, relative humidity, and propagation distance. This function uses equations published by Bass et al. to calcuate the attenuation of sound for the input parameters. The function returns the attenuation in decibels. Platforms: Matlab

This application can be used to easily calculate the resistor values needed to achieve a specified attenuation in a controlled impedance environment. Platforms: Windows

This function file is basically for Passive Butterworth Filter for Low pass as well as for High Pass. In input it takes the Pass Band Attenuation, Band Stop attenuation, Band Pass Frequency, band stop frequency, and Filter Type. For Low Pass Type is "0" and for High Pass Type is "1".It finally...
