We can prove that, at least 50% (often close to 2/3) of the total transmitted power resides in a carrier term that is independent of the signal and thus conveys no message information. (what a waste!). Digital data must be modulated on an analog signal that has been manipulated to look like two distinct values corresponding to binary 1 to binary 0. Digital To Analog Conversion. Digital To Analog Conversion. Lecture Learning Outcomes. Be able to understand, appreciate and differentiate the different signal encoding criteria available.. Class Contents. Signal Encoding Criteria. Digital Data, Analogue Signals. 1. Introduction. 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, . Analog data to analog signal. (AM, FM, PM).

Operation of varying amplitude, frequency or phase of carrier signal accordingly with the instantaneous amplitude of the message signal.. In FH-SSS, the carrier frequency is changed randomly according to a PN code. FH-SSS is used for mobile civilian and military tactical communications. According to the hop rate ( hop rate is the speed of hopping, which is the number of times the carrier frequency is changed per second), and its relation to the data rate, FH-SSS systems are classified into: .
