Then, you need to be able to identify which journals are peer-reviewed. There are generally four methods for doing this: 1  Limiting a database search to peer-reviewed journals only. 2  Some databases allow you to limit searches for articles to peer reviewed journals only.
A walkie-talkie (more formally known as a handheld transceiver, or HT) is a hand-held, portable, two-way radio transceiver. Its development during the Second World War has been variously credited to Donald L. Hings, radio engineer Alfred J. Gross, and engineering teams at Motorola.
This example shows how to implement a walkie-talkie receiver using SimulinkÂ® and Communications System Toolboxâ¢. The specific radio standard that this example follows is FRS/GMRS (Family Radio Service / General Mobile Radio Service) with CTCSS (Continuous Tone-Coded Squelch System). You can use simulated signals, captured signals, or received signals from a commercial walkie-talkie using the Communications System Toolbox Support Package for RTL-SDR Radio.
