Resonance: Reinforcement and prolongation of a sound or musical tone by reflection or by sympathetic vibration of other bodies.
Superheterodyne Receiver : Donating a device or method of radio reception in which beats are produced by superimposing a locally generated radio wave on an incoming wave. In the superheterodyne receiver the intermediate frequency is amplified and demodulated.
Tone Burst Generators In Research Tone burst generators are often used in high power ultrasonic applications. They take low-voltage signals and convert them into high-power pulse trains for the most power-demanding applications. Their purpose is to transmit bursts of acoustic energy into a test piece, receive the resulting signals, and then manipulate and analyze the received signals in various ways. High power radio frequency (RF) burst capability allows researchers to work with difficult, highly attenuative materials or inefficient transducers such as EMATs. A computer interface makes it possible for systems to make high speed complex measurements, such as those involving multiple frequencies.
