Title: Modulator
Inventor: ADACHI MASARU
IPC: H04L27/20
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To output a non-modulated carrier signal of a level higher than the peak signal of a data signal without deteriorating an S/N in a modulation signal even if the resolution of a DA converter is not improved by providing a variable gain unit for the output stage of the DA converter. SOLUTION: When the non-modulated carrier signal is outputted, an orthogonal component Q (t) is set to 'O' and DC value data equivalent to non- modulated carrier signal power to be outputted is outputted from an in-phase component I (t). The variable gain unit 11 is provided for the poststage of the DA converter 3. When the non-modulated carrier signal is outputted, the gain of the variable gain unit 11 is set higher than that at the time of outputting the modulation signal in accordance with modulation/non-modulation switch signals from a modulation signal generator 1. Thus, a modulation signal peak value can be set to the largest input range of the DA converter 3, and the non-modulated carrier signal of the high level can be outputted by securing the maximum SN which the DA converter 3 can take for the modulation signal as it is (without deteriorating the S/N).
