Abstract
Frequency shift keying (FSK) is an old but powerful form of modulation that powered much of the early modems of the 1960’s, and the author felt inspired to make his own version of audio binary FSK modulation. He researched the general history and legacy of the Bell 103, a modem using FSK that defined telecommunication for the next few decades. Using research of the most common English characters of recent emails to determine which English characters should have the shortest bit length, a novel character encoding standard was created using variable bit rate. In addition, he has created a modulation and demodulation project in Python using this new encoding standard, with the addition of a mark and rest tone to apply the variable bit rate encoding to increase the throughput of transmitted data, and to eliminate noise that could interfere.
