摘要： The present invention relates to an amplitude modulation apparatus, an amplitude limiting method, and a transmission apparatus for performing amplitude limitation on an orthogonally modulated signal. The amplitude modulation apparatus, the amplitude limiting method, and the transmission apparatus enable peak value suppression of a transmission wave with a simple structure. An amplitude limiting apparatus that performs amplitude limitation on an orthogonally modulated signal includes first amplitude limiting means (31, 32) for limiting to predetermined amplitudes the amplitudes of an I-component and a Q-component of the orthogonally modulated signal that are orthogonal to each other, and second amplitude limiting means (33-41) for performing further amplitude limitation on the I-component and the Q-component according to the difference between the amplitude-limited I-component and Q-component obtained by the first amplitude limiting means.

摘要： An operation input device includes an operation member that includes an operation surface having an outer edge part and is configured to be displaced downward by an input operation force exerted on the operation surface, a yoke attached to the operation member, a coil that detects a position of the operation member based on a position of the yoke and outputs a signal corresponding to an amount in which the operation member is displaced downward, and an engagement part that is positioned below the operation member and configured to contact the operation member at a contact position immediately below the outer edge part of the operation member. The engagement part is configured to constrain the operation member so that the operation member is not displaced further downward than the contact position when the engagement part contacts the operation member.
