The term communication (or telecommunication) means the transfer of some form of information from one place (known as the source of information) to another place (known as the destination of information) using some system to do this function (known as a communication system).
Communication channels are mediums through which you can send a message to its intended audience. For example, phone calls, text messages, emails, video, radio, and social media are all types of communication channels. In a company, communication channels keep information flowing efficiently
More seriously, signals are functions of time (continuous-time signals) or sequences in time (discrete-time signals) that presumably represent quantities of interest. Systems are operators that accept a given signal (the input signal) and produce a new signal (the output signal). Of course, this is an abstraction of the processing of a signal.
The Hilbert transform of g(t) is the convolution of g(t) with the signal 1= t. It is the responsetog(t) of a linear time-invariant lter (called a Hilbert transformer) having impulse response1= t. The Hilbert transformH[g(t)] is often denoted as g(t)^ or as [g(t)]^.
