Patent Number Title Of Patent Date Issued
4216354 Process for compressing data relative to voice signals and device applying said process August 5, 1980
A voice signal is transmitted digitally at reduced bit rate by use of data compression. The original frequency components of a telephone band width of the voice signal sampled at 8 KHz and quantized with 12 bits are transformed into three parameters: SIGNAL data representing adaptive
4051470 Process for block quantizing an electrical signal and device for implementing said process September 27, 1977
This is a block quantizer which converts a given block of samples into an optimum sequence of numbers describing the sampled signal with minimum distortion due to the quantizing process.The quantizer self-adjusts the basic parameters, i.e., quantizing step Q, d.c. level C and the sequenc
