Receiver (modulated ultrasound), a device that converts a modulated ultrasound signal into useful information
Receiver (hearing aids), a transducer in hearing aids responsible for converting the electric input signal into an acoustic output signal; see also hearing aid
AMPLIFIER
In general, an amplifier is any device that uses a small amount of energy to control a larger amount of energy. In popular use, the term today usually refers to an electronic amplifier, often as applied to audio applications. The relationship of the input to the output of an amplifier — usually expressed as a function of the input frequency — is called the transfer function of the amplifier, and the magnitude of the transfer function is termed the gain.
receiver has a tuner (radio stations),
amplifier doesn't
A receiver picks up the native signal and the amplifier boosts the signal and sends it out.
A receiver is basically an amplifier with a radio tuner built in. Modern receivers are normally those of the home cinema type, these have multichannels for surround sound. They normally have inputs for dvd, cable, games consoles etc.Most amplifiers are 2-channel (stereo) and will generally offer better sound quality over a similarly priced receiver, for those who just want to listen to music.
