Latest Patents
The patent held by John F. Siebenand is titled "Speech Sampling and Companding Device." This invention involves an analog speech signal that is sampled at a nominal rate of 6 kilohertz and digitized using a Mu-Law Encoder. The digital output from the encoder undergoes conversion by a microprocessor, which performs table look-up to generate linearized pulse code modulation (PCM) samples, typically represented as eight bits per sample.
Utilizing a technique known as Block Scaled Pulse Code Modulation (BSPCM), the invention processes blocks of approximately 246 eight-bit PCM samples, representing around 41 milliseconds of audio. By determining the maximum and minimum sample values within each block, a scale factor is calculated. This innovation adjusts the bit rate by optimizing the step size, thereby efficiently compressing the audio signal for improved processing and transmission over telephone systems.
