TELEMETRY SYSTEM EMPLOYING DC BALANCED ENCODING

摘要

A telemetry system including a first device having a processor that employs a DC balanced encoding scheme to generate a DC balanced encoded data signal, a modulator for modulating an RF carrier wave by the DC balanced encoded data signal and generating a DC balanced encoded RF modulated data signal includi ng DC balanced RF energy. The DC balanced encoded RF modulated data signal transmitted by the first device is received by a second device. Since the RF energy received is DC balanced, drift in baseline voltage is eliminated irrespectiv e of data transmission thereby improving the robustness of recovery of data by the second device. The second device may include a converter for converting the DC balanced RF energy extracted from the received DC balanced encoded RF modulated da ta signal to a substantially constant average induced voltage, irrespective of data being transmitted, for powering at least one component of the second device.
