Use it with logic circuits or as an audio or RF signal generator. Gary McClellan 51/10 October 1980 Unicorn-1 robot Part 3. Design and construction of the mobility base. James A. Gupton, Jr. 51/10 October 1980 Circuit design station Prototype and debug your circuits using this battery-powered design station. James Barbarello 51/11 November 1980
Forrest M. Mims III is an American amateur scientist, [2] magazine columnist, and author of Getting Started in Electronics and Engineer's Mini-Notebook series of instructional books that were originally sold in Radio Shack electronics stores and are still in print.
Basic automatic frequency control in a radio receiver. У = RF amplifier stages, Д = frequency discriminator stage. In radio equipment, Automatic Frequency Control (AFC), also called Automatic Fine Tuning (AFT), is a method or circuit to automatically keep a resonant circuit tuned to the frequency of an incoming radio signal.
MacLoggerDX is a full-featured amateur radio contact logger for macOS with Transceiver control, Rotor control, Callbook lookup, QSL handling (Hardcopy / LoTW / eQSL / Club Log), DX Cluster and spotting, and basic contesting support.
An AM radio made from a Snap Circuits kit. Snap Circuits is a line of electronic kits manufactured by Elenco Electronics and aimed at children eight years and older. [1] The kits come in a variety of sizes, and may include capacitors, diodes, electric motors, lamps, LEDs, radios, electromagnets, speakers, resistors, transformers, transistors and voltmeters.
The ZN414 is a low cost, single-chip AM radio integrated circuit. Launched in 1972, the part was designed and supplied by Ferranti , but was second sourced from GEC-Plessey . The ZN414 was popular amongst hobbyists, as a fully working AM radio could be made with just a few external components, a crystal earpiece and a 1.5 V cel l.
Software-defined radio (SDR) is a radio communication system where components that conventionally have been implemented in analog hardware (e.g. mixers, filters, amplifiers, modulators/demodulators, detectors, etc.) are instead implemented by means of software on a computer or embedded system. [1]
Correspondingly, the voltage noise of a resistance R into an open circuit is ) / and the current noise into a short circuit is /) /. The noise figure is defined as the ratio of the noise power at the output of the amplifier relative to the noise power that would be present at the output if the amplifier were noiseless (due to amplification of ...
