Analog transmission is not particularly efficient. When the signal-to-noise ratio of an analog signal deteriorates due to attenuation, amplifying the signal also amplifies noise. Digital signals are ...

Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...

This paper presents the Adaptive Differential Pulse Code Modulation (ADPCM) method of digitally storing and reproducing speech or other waveforms. A detailed explanation of the encoding steps is given ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

A North American telephony standard for converting analog voice into a digital data stream using pulse code modulation (PCM). The "pulse code" in PCM comes from the telephone company's method of ...

[Dave Jones] from EEVBlog.com takes “Arduino fan boys” off the garden path getting down and dirty with different methods to capture, evaluate and retransmit IR remote control codes. Capturing and ...
