Abstract

According to an embodiment, a digital transmitter () includes an amplitude modulation amplitude signal generation unit () that generates a function f(A(t)) of an amplitude signal A(t) as an amplitude modulation amplitude signal A'(t), an amplitude modulation phase signal generation unit () that calculates 'cos{A(t)/f(A(t))}' as a phase θ() and generates amplitude modulation phase signals P() and P(), an individual digital transmission unit () that generates an amplified RF-pulse signal based on the signals A′(t) and P(), an individual digital transmission unit () that generates an amplified RF-pulse signal based on the signals A′(t) and P(), and an RF-synthesizer () that combines outputs of the individual digital transmission units () with each other.
