Against the precipitous backdrop of funding cuts to public media, low-power radio emerges as a lesser-known source of ...

Abstract: This paper investigates the front-end hardware circuit of an Arbitrary Waveform Generator (AWG). To reduce the demand for ADC sampling rates, a spectrum signal stitching system was ...

Shannon’s sampling theorem states that a signal of frequency f can be fully captured by sampling at 2f. Modern PC sound cards support rates up to 192 kSamples/s, sufficient for signals below 96 kHz.

In 1977, the Ohio State University’s Big Ear radio telescope received an unusually strong narrowband radio signal, leading to widespread excitement about the possibility of having encountered evidence ...

BBC fans who tuned into the latest episode of Only Connect were left complaining over a team leader's rather annoying habit. During Monday's episode (September 29), Victoria Coren Mitchell hosted the ...

Abstract: A generation of orthogonal signals in single-phase systems, crucial for various applications such as power converters synchronization, faces challenges in handling disturbances like DC ...
