Abstract: System and method for correcting a phase noise generated by vibration of an antenna transmitting or receiving a radio frequency (RF) signal in a signal propagation direction includes: measuring the vibration of the antenna by a sensor generating an output signal; converting the output signal of the sensor to a measurement signal proportional to the vibration of the antenna in the signal propagation direction; performing a single or double integral of the measurement signal to produce a control signal with an amplitude proportional to the vibrational velocity or displacement of the antenna in the signal propagation direction; and applying the control signal to an oscillator, a clock signal, or a phase controller associated with the RF signal.

Abstract: A musical tone generating apparatus employs an array of microresonant structures to generate the harmonic component signals of a musical tone to be generated. The microresonant structures produce high frequency signals which are down converted to audio frequency range by mixing them with a high frequency reference signal. The desired tone color is achieved by modifying the relative amplitudes of the harmonic component signals to produce a desired tone color. A large number of microresonators are preferably integrated on a single integrated circuit substrate to provide a variable tone generating system in a relatively compact environment.
