Procedures •Open the simulation. •Explain how the radiating electric field (or electromagnetic signal) is produced when radio stations broadcast. A radio wave (radiating electric field) propagates out from the source‚ traveling at the speed of light. The source‚ for example an antenna‚ creates oscillating electric(E)/ magnetic(B) fields. These fields are perpendicular not only to each

How to Solder First a few safety precautions: * Never touch the element or tip of the soldering iron. They are very hot (about 400°C) and will give you a nasty burn. * Take great care to avoid touching the mains flex with the tip of the iron.

ABSTRACT: The RF relay control‚ as the name suggests‚ operates at Radio Frequency. The corresponding frequency range varies between 30 kHz & 300 GHz. In this RF system‚ the digital data is represented as variations in the amplitude of carrier wave. This kind of modulation is known as Amplitude Shift Keying (ASK). Transmission through RF is better than IR (infrared) because of many reasons. Firstly‚ signals through RF can travel through larger distances making it suitable
