PDF-Chapter Traditional Analog Modulation Techniques Mikael Olofsson Modulation techniques

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. :.

A digital signal is superior to an analog signal because it is more robust to noise and can easily be recovered, corrected and amplified. For this reason, the tendency today is to change an analog signal to digital data. In this section we describe two techniques, . Amplitude Modulation (AM). Time domain equation. y. AM. (t. ) = .
