- Binary Amplitude Shift Keying
- License: Freeware

This script simulates the Binary Amplitude Shift keying. Since BASK is a digital modulation scheme, you can modulate as many bits as you want. however, I have only simulated it for 5 bits, so that the results are visible. This is code for BASK only, means it can only modulated two digital states. I hope this will help out students and instructors alike..

- Amplitude Imposer
- License: Shareware

Takes 2 stereo inputs and imposes the amplitude envelope of the first one on the second one. Also has a Threshold level for the second input, so that when the signal falls below it, it is amplified up to the threshold, to give a greater signal to be amplitude modulated. You'll need a relatively flexible host (i.e. one that allows you to have 4 inputs and 2 outputs for an effect)..

- Amplitude Modulation
- License: Freeware

The codes in two files generate time and frequency domain representation of three basic types of amplitude modulation i>Double SideBand Amplitude Modulation (Full Carrier) (DSBAM) ii>Double SideBand Suppressed Carrier (DSBSC) iii>Single SideBand (SSB) The message signals used are combination of sinusoids of different frequency. Most authors use single tone modulation so give the initial concepts, but rarely do any one of them go beyond than. I believe the multi tone modulation representation will help in visualizing how AM will work in case of voice modulation, which certainly is composed of number of harmonics.
