This demo video shows using a Rigol DG4000 Series Arbitrary Waveform Generator and a DSA1000 series of Spectrum Analyzer to create and demodulate an FM audio transmission. This demo video shows using ...

The completed composite demodulator with wall wart. At the end of the pipe in every FM station operating in stereo — which probably is 99.5% of the over 7,000 FM outlets operating here in the United ...

SAN DIEGO—A local San Diego low-power TV station is testing the broadcast of FM signals over ATSC 3.0 (aka "NextGen TV"). KRPE-LD San Diego, low power TV channel 6, atop Mt. San Miguel, is the first ...

WE have examined further the anomalous fluctuations in the superconducting bolometers previously reported by Andrews, Milton and Desorbo 1, and find that, in part, such fluctuations are due to the ...

Many serious machine problems can be diagnosed early with normal vibration analysis techniques based on fast Fourier transforms. But some problems remain dangerously hidden in the vibration reading — ...

Overcoming the issues of DC offset in Direct Conversion for Software Defined Radios. Modulation is a process by which characteristics of a high-frequency carrier signal are altered to convey ...

Lock-in amplifiers let you measure very small signals that would otherwise get lost in the noise of even the best available amplifiers. Originally analog circuits, lock-in amplifiers have evolved into ...
