The heaviest price speculation has been around the high-end, 18-karat gold Apple Watch (dubbed âApple Watch Editionâ).
In electronics, a multiplexer (or mux) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line. A multiplexer of 2 inputs has n select lines, which are used to select which input line to send to the output.
Transducers (such as optical or magnetic encoders) sense position or orientation for use as a reference or active feedback to control position: A rotary encoder converts rotary position to an analog (e.g., analog quadrature) or digital (e.g., digital quadrature, 32-bit parallel, or USB) electronic signal. A linear encoder similarly converts linear position to an electronic signal. Such encoders can be either absolute or incremental.
