Pulse density modulation (PDM) is a compact digital audio format used in devices like MEMS microphones and embedded systems. This compact primer eases you into the essentials of PDM audio. Let’s begin ...

In most business environments, telephone calls are typically handled by a receptionist or directed to specific extensions using an internal intercom system. The technology enabling this seamless ...

Moment-to-moment neural variability has been shown to scale positively with the complexity of stimulus input. However, the mechanisms underlying the ability to align variability to input complexity ...

Anthony is a Toronto-based communications specialist with degrees in history and journalism who loves to use his research and interview skills to inform and entertain. He has over a decade of ...

Abstract: Speech coding is important for effective storage and transmission of audio signals. However, current Interactive Multimedia Association Adaptive Differential Pulse Code Modulation (IMA-ADPCM ...

Cochlear implants (CIs) provide important speech cues to deaf patients, but they fail to support the discrimination of temporal sound features with submillisecond precision. Although CIs rapidly and ...

This code example shows how to use single slope Pulse-Width Modulation (PWM) in the Timer/Counter A (TCA) on the AVR® DB Family of microcontrollers to generate overflow interrupts that toggle a LED.

In order to solve the problem of low gray level due to the few driving chips developed based on the photoelectric characteristics of electrowetting display, a driving method based on modulation is ...

A Microchip Technology PIC microcontroller can be an accurate solution for calculating the timing of a pulse-width modulation (PWM) signal due to its architecture. With this design, you can measure ...

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 ...
