Analog Data Compression for Versatile Experimental Kevlar Array (VEKA) Telemetry.

Abstract

The feasibility of amplitude data compression has been explored with respect to the Versatile Experimental Kevlar Array (VEKA) analog multiplexed telemetry of acoustic data. A Fourier transform approach has been developed to quantify the potential benefits and penalties associated with a particular invertible compression function. Analysis was performed using sinusoidal signals and white noise. Results of the analysis indicate that substantial gains in dynamic range can be achieved with tolerable sacrifices in telemetry system linearity. Specific examples for a particular telemetry system illustrate an increase in dynamic range from 80dB to approximately 120dB. (Author)
