Abstract

In some embodiments, a transmitter includes first encoding controlled frequency output circuitry to creates a magnitude encoded controlled frequency signal (CFS) and second encoding controlled frequency output circuitry to create a complementary a magnitude encoded controlled frequency signal (CCFS). Other embodiments are described and claimed.
