Introduction A general system (device) has one or more inputs and a processor that processes the input(s) and generates one or more outputs. Input and output can be of the same or different netures. Processor Output 1 Output n Input 1 Input m Examples: Light Bulb; Input: Output: Processor: Microphone; Input: Output: Processor: Calculator; Input: Output: Processor: In this course we learn about devices that manipulate binary signals and are called "Binary Logic Circuits". 2/10 Atousa Hajshirmohammadi, SFU Lecture 2
Binary Signals A “binary signal” is a signal (data) that can takes only two values. We can call these values {0,1}, or {off, on} or {false, true} or {low, high}, etc. Basic elements used in digital circuits are “transistors” which work with
