Abstract
Although data compression methods exist in the prior art, some of which would result in an optimal number of piecewise linear approximation segments for the compressed output signal, these compression methods require complicated calculations and data processing that inhibit real time signal processing and portability in hardware implementation. A novel method for signal compression with a known level of loss by selecting a level of acceptable error is described. With this new compression method, the number of additional approximation segments to its compressed output signal is generally 50% more than the optimal number obtained in the prior art. However, its processing simplicity allows for improved real time signal processing and simplified practical hardware implementation.
