A magnet is an object that has a magnetic field. It can be in the form of a permanent magnet or an electromagnet.
A microprocessor (sometimes abbreviated µP) is a programmable digital electronic component that incorporates the functions of a central processing unit (CPU) on a single semiconducting integrated circuit (IC).
A DCC decoder intended for fitting in a loco.
Is the process of superimposing information onto a pure sine wave (Carrier wave), this process can be achieved by any of fourmethods, amplitude (AM), frequency (FM), Phase (PM) or Pulse (PAM, PWM, or PPM)
metal-oxide-semiconductor field-effect transistor MOSFET
A communications device that multiplexes (combines) several signals for transmission over a single medium. A demultiplexor completes the process by separating multiplexed signals from a transmission line. Frequently a multiplexor and demultiplexor are combined into a single device capable of processing both outgoing and incoming signals.
A multiplexor is sometimes called a mux and also spelled as multiplexer.
