ABSTRACT:
A telemetry system which will transmit data at a relatively high rate while retaining a high degree of accuracy is disclosed which utilizes a servo feedback loop in conjunction with a conventional reflected impedance receiving front end parallel LC circuit, an AM demodulator, and an oscillator to drive the LC circuit at a desired frequency. The feedback loop operates to keep the voltage across the LC circuit constant over time, and does not affect short term variations in the voltage across the LC circuit which are caused by the variations in the reflected impedance. While frequency response of the system without the loop declines from a maximum value at zero frequency, the frequency response of the system of the present invention with the loop is shifted which permits data transmission at a substantially higher rate.
