Data and Signals Data must be transformed to electronic signals (why?) Analog data: Continuous information, e.g., voice has a value at any time. Analog clock have values at any time! Digital data: Discrete state information. e.g., digital clock. Analog signal: They have infinitely many levels over a period of time. Digital signals: They have limited number of defined values. Periodic Signals: “Repeat a pattern every measurable time frame,

Unformatted text preview: “period” or “cycle”. (most used for analog signals) Non-Periodic (Aperiodic) Signals: No pattern or cycle. (most used for digital signals) Periodic Analog Signals Frequency (f) = 1/T and T = 1/f Phase: It is the position of waveform relative to time = 0. Ex: The “sine” phase is 0, where as the “cos” phase = π /2...
