This “coding gain” tends to average out the ISI and minimize its effect. Figure 23. Chebyshev Equiripple FIR Filter 4.7 Spectral efficiency versus power consumption As with any natural resource, it makes no sense to waste the RF spectrum by using channel bands that are too wide. Therefore ...
Some form of line coding or scrambling is needed to prevent long runs of 1s or 0s in the transmitted data stream to allow the clock to be recovered easily at the receiver and to maintain DC balance. Subcarrier multiplexing is a technique in which many signals are electronically multiplexed ...
Information is the source of a communication system, whether it is analog or digital. Information theory is a mathematical approach to the study of coding of information along with the quantification, storage, and communication of information.
Channel coding encodes the data in such a way as to minimize the effects of noise and interference in the communications channel. Channel coding adds extra bits to the input data stream and removes redundant ones. Those extra bits are used for error correction or sometimes to send training ...
The events selected in the HRTIM_RESETxyR register are coding for both the output reset during up‐counting and the output set during down‐counting. This allows the creation of more complex waveforms, as shown on ...

Since the coefficients are coded with different sets of quantizers (according to Nsi (j)), it is necessary to include the relative performance values of each set of quantizers in the allocation of the bits, according to the work by Jayant and Noll, Digital Coding of Waveforms (Prentice ...
