PROBLEM TO BE SOLVED: To reduce EMI noise that is generated in entire equipment, by reducing EMI noise in accordance with a module that is being driven.SOLUTION: An electronic circuit includes: a plurality of modules including a display module; a control part which transmits a pulse signal for driving to the plurality of modules; an EMI frequency storage part for storing a frequency of an EMI noise component in a pulse signal that is transmitted from the control part to any other module than the display module, correspondingly to the other module; and a settable range detection part which detects a settable range of a frequency of a pulse signal to be transmitted from the control part to the display module. When transmitting a pulse signal to the display module, the control part sets a frequency that excludes frequencies of noise components being stored correspondingly to the other modules being driven and is within the detected settable range, as the pulse signal to the display module.SELECTED DRAWING: Figure 3 |
