A binary ASK transmitter and receiver is designed to transmit digital information over a "speaker-air-microphone" (SAM) channel. Listening to the channel while making parameter adjustments and viewing plots builds additional insights into the ASK modulation scheme. This project describes the various tradeoffs affecting bandwidth and information rate and provides an application for the pulse shapping transmit filter.
Texting and instant messaging are familiar and popular communication techniques. Text messages composed of ASCII characters, with each character composed of eight bits, ultimately form a stream of bits transmitted from the source to the receiver. Normally the text message moves through a complex data network, and the user only sees the endpoints of the system. In this project, however, you will be able to follow the text message on its complete journey through a binary ASK transmitter, a speaker-air-microphone (SAM) channel, and a binary ASK receiver.
