Fourier Transform And Its Application In Modulation Techniques. Amplitude Modulation and its Applications Amplitude Modulation is an electronic communication systems technique wherein the baseband signal is superimposed with the amplitude of the carrier wave i.e. the amplitude of the carrier wave is varying with proportion to the base waveform being transmitted., WLAN and WBA applications in the unlicensed spectrum use the frequency band known as “2.4 GHz” (ranging from 2.4 GHz to 2.4835 GHz, same as the Industrial, Scientific and Medical - ISM band)..

the frequency of the transmitted signal must be quite high compared to the frequency of the information signal. For example, the signal in a cell phone is a voice signal with a bandwidth of about 4 kHz. The typical frequency of the transmitted and received signal is several hundreds of megahertz to a few gigahertz (for example, the popular WiFi standard is in the 2. 4 GHz or 5+ GHz range). 199 Amplitude Modulation and its Applications Amplitude Modulation is an electronic communication systems technique wherein the baseband signal is superimposed with the amplitude of the carrier wave i.e. the amplitude of the carrier wave is varying with proportion to the base waveform being transmitted.

FSK is a form of constant-amplitude angle modulation similar to standard frequency modulation (FM) except the modulating signal is a binary signal that varies between two discrete voltage levels rather than a continuously changing analog waveform. Consequently, FSK is Frequency Modulation Span This parameter is defined as the maximal frequency span that VCO may cover when driven by modulating signal. With VCOs there is no actual limit to the span and a VCO can support WBFM starting at its lowest frequency and ending at its highest frequency.
