1.1 What is a signal? A signal is formally defined as a function of one or more variables that conveys information on the nature of a physical phenomenon. one dimensional (depend on single variable) — e.g. speech signal one dimensional (depend on single variable) — e.g. speech signal Multidimensional (depend on two or more variable)– e.g. image singnal (two dimensional)Multidimensional (depend on two or more variable)– e.g. image singnal (two dimensional) 1.2 What is a system? Figure 1.1 (p. 2) Block diagram representation of a system. A system is formally defined as an entity that manipulates one or more signals to accomplish a function, thereby yielding new signals.
