2 Signals • A signal is a variable physical quantity by which a message or information can be represented – A function of one or more independent variables, such as x(t). •Examples: – Voice, blood pressure, temperature, … Systems • A system is a “black box” that transforms an input signal (signals) to an output signal (signals).

3 Objectives • Describe signals – x(t) and y(t) • Characterize system H • Analysis: given a system H and its input x(t), find the resulting output y(t) • Synthesis (design): given an input x(t) and a desired output y(t), design the required system H Tools – Time domain analysis: convolution – Fourier methods: frequency analysis – Laplace transform: transient response and stability
