Abstract
In a magnetic resonance measurement apparatus, a plurality of transmission signals are combined to generate a digital combined signal. The digital combined signal is converted into an analog combined signal by a D/A converter. The signal includes, for example, a first pulse of a rectangular shape and a second pulse of a mountain shape. During measurement, an operation of a dynamic variable attenuator is changed immediately after the first pulse. With this process, the second pulse is suppressed, and a suppressed second pulse is generated.
