Flashcards
Analog Signals
Analog Signals
Signals that continuously change their values over time. They can be of any value within a range. Examples include sound waves, temperature readings, and light intensity.
Digital Signals
Digital Signals
Signals that are represented by discrete values, typically using binary digits (0 and 1). They are created by converting analog signals to digital form.
Thermocouple
Thermocouple
A device that converts thermal energy (heat) into electrical energy. The output voltage or current changes proportionally with temperature changes.
