A novel signal quantization scheme based on adaptive differential pulse code modulation (ADPCM) is proposed and experimentally demonstrated. By adaptively adjusting the quantization step size using a ...

A project focused on sampling, pulse code modulation (PCM), and adaptive differential pulse code modulation (ADPCM) techniques using MATLAB. The implementation includes signal conversion and bit rate ...

Abstract: We propose a digital-cascaded-pulse-code-modulation radio-over-fiber (DCP-RoF) scheme and verify it experimentally in a coherent transmission system. The 50-Gbaud 2-order 6-bit DCP-RoF ...

Modulation in the temporal pattern of transcutaneous electrical nerve stimulation (TENS), such as Pulse width modulated (PWM), has been considered a new dimension in pain and neurorehabilitation ...

Pulse Width Modulation (PWM) is a technique used to control the intensity of a signal or digital output through the manipulation of its duty cycle. Initially developed for use in audio equipment, PWM ...
