Aspects of this disclosure relate to a radio frequency system that includes an envelope generator configured to generate an envelope signal corresponding to an envelope of a radio frequency signal and at least two radio frequency components coupled to the envelope generator. One of the radio frequency components is a radio frequency switch configured to pass the radio frequency signal. The radio frequency switch is configured to receive the envelope signal to cause intermodulation distortion associated with the radio frequency switch to be reduced.

An apparatus to detect, analyze, record, and display audio data, including an input unit to allow a user to input musical notes corresponding to the audio data, a processor to analyze the musical notes and to save the musical notes into a file, and a display unit to display notes corresponding to the musical notes on a virtual instrument.

Aspects of this disclosure relate to a switching circuit with enhanced linearity. The switching circuit can include a switch and an envelope generator. The switch can receive an input signal, provide an output signal, and receive an envelope signal corresponding to an envelope of the input signal. The envelope generator can generate the envelope signal so as to cause intermodulation distortion in the output signal to be reduced to cause linearity of the switch to be improved.

A sound control device includes: a detection unit that detects a first operation on an operator and a second operation on the operator, the second operation being performed after the first operation; and a control unit that causes output of a second sound to be started, in response to the second operation being detected. The control unit causes output of a first sound to be started before causing the output of the second sound to be started, in response to the first operation being detected.

A musical sound signal generation device continuously connects any one of a connected zeroth delay unit and a connected second delay unit to a fractional delay block and connects at least any one of a new zeroth delay unit and a new second delay unit to at least any one of the fractional delay block other than the fractional delay block connected to a new first delay unit in response to setting any one of the connected zeroth delay unit and the connected second delay unit as the new first delay unit, setting a delay unit in a preceding stage of the new first delay unit as the new zeroth delay unit, and setting a delay unit in a subsequent stage of the new first delay unit as the new second delay unit in accordance with a change in a designated tone pitch.
