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 ...

Although the electromagnetic spectrum is a continuum, a strong distinction is typically drawn between electronics and optics. This distinction is due, in part, to the very different technologies used ...

Abstract: Several research communities have presented innovative approaches to the challenge of generating complex waveforms required to evaluate new ultrasonic transmission techniques. Dedicated high ...

The circuit to create waveform like this is based upon a simple relay that is driven by a clock signal.

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 ...

Abstract: The multisource inverter (MSI) serves as a high-efficiency interface for hybrid energy electric vehicles by eliminating the need for intermediate dc–dc converters. Nevertheless, modulation ...
