PROBLEM TO BE SOLVED: To provide a transmitter in which spurious contained in a signal to be transmitted is reduced.SOLUTION: A transmitter includes a pulse generation unit 10 generating pulses rising or falling alternately, every time when a signal value contained in a transmission signal reaches a predetermined value, a first waveform shaping unit 15 having one or a plurality of inverters 15a connected in series, and shaping the rising waveform or the falling waveform of a pulse generated in the pulse generation unit 10, a second waveform shaping unit 20 arranged between the input and output of at least one inverter 15a, and shaping the pulse so that the inclination of the rising waveform of a pulse outputted from the inverter 15a approaches the inclination of the falling waveform, and a bandpass filter 16 for passing a predetermined band width of the pulse shaped by the first waveform shaping unit 15 and second waveform shaping unit 20. |
