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.
