FSK is a commonly used technique for trans- mission of digital data in low cost applications. Unfortunately, several problems are associated with using direct FM. Noise immunity is compromised when the DC component of the incoming data is not near zero. Moreover, there is no direct method for synchronization or clock recovery. Data encoding techniques, such as Manchester Encoding and Alternate Mark Key Encoding, are often used to resolve these problems.
