Name: Speaker-Air-Microphone (SAM) Channel Characterization
ID: m18666
Language: English (en)
Summary: A speaker and microphone connected to a computer serve as an excellent communications channel because the transmitted information is audible. Listening to the channel while making parameter adjustments and viewing plots builds additional insight into the specific modulation scheme under study. This project describes how to characterize a "speaker-air-microphone" (SAM) channel for use in subsequent projects that use bandpass modulation techniques.
