PPT-Modulation Techniques for Mobile Radio

Modulation is the process of encoding the baseband or source information voice video text in a manner suitable for transmission It generally involves translating a baseband signal or source to a band pass signal centered at a high carrier frequency. 0 BASIC TECHNIQUE This application note describes a technique for creating an analog to digital converter using a microcontroller with other low cost components Many applications do not require the speed associated with a dedicated hardware AD conver The reason for that may be that the channel is bandlimited or that we are assigned a certain frequency band and frequencies outside that band is supposed to be used by others Therefore we are interested in the spectral properties of v arious modulat Introduction. 1.

Radio-Frequency Identification (RFID) is the use of radio waves to read and capture information stored on a tag attached to an object.  A tag can be read from up to several feet away and does not need to be within direct line-of-sight of the reader to be tracked. .
