There’s a transformer for the linear supply, through-hole components, and an Intersil frequency counter on a chip. Everything is easy to get to and large enough to see.

[Debraj] needed a simple signal generator for a project he was working ... he observed that the PC had good frequency fidelity, though it required an additional DC offset as most cards are built ...

Description: signals; select the frequency for site, tracing range Ease-of-use, default output frequency of 33K power level 2 Clear, audio visual controls; externally mounted, displaying the ...

This is the frequency of the wave. Morrison and Cocconi considered how well the types of electromagnetic waves passed through interstellar space. While space is usually described as a vacuum, it does ...

The frequency illusion, also called the Baader-Meinhof phenomenon, is a cognitive bias in which someone learns a novel word or concept—and then “suddenly” encounters it everywhere ...

Description: measurements in remote locations Built-in analog output of 1mV per count SPECIFICATIONS: Measuring Range: 30 to 130 dB(A); 35 to 130 dB(C) Resolution: 0.1 dB Accuracy: ±0.7 dB after ...

Frequencies are in kiloHertz (kHz). 1 MegaHertz (MHz) is equal to 1000 kHz. Conversion to meter bands: Meters=300000/frequency in kHz. e.g.: 17705 kHz --> 16.9 meters ...

The allele frequency represents the incidence of a gene variant in a population. Alleles are variant forms of a gene that are located at the same position, or genetic locus, on a chromosome.

Binaural beats, when tuned to an adequate frequency, are theorized to encourage the brain to gradually transition from a more alert, higher-frequency state into a slower, more relaxed one. Some ...

To get things up and running again, you need a portable generator. The quietest, lightest, and most powerful 2,200-watt generator we tested is easy to start, and the Bluetooth app makes monitoring ...

Weather radios are designed to broadcast special frequencies and alert owners of hazards. The weather radio you buy can be set to silent until a warning of your choice occurs, at which point ...
