Wideband precision analog telemetry link using digital techniques
Abstract
A highly linear Wideband Analog Fiber Optic Link is described which samples at a 1 MHz rate with 10-bit accuracy and transmits and receives by means of a high speed PDM code. Aliasing and sampling effects are fully suppressed and a nearly Gaussian pulse response is attained with a 2 micro sec risetime. Analog signals are recovered with very low distortion and d.c. drift and a S/N ratio of better than 52 db.
