Title:
ＰＷＭ信号発生器
Document Type and Number:
Japanese Patent JP5833047
Kind Code:
B2
Abstract:
An embodiment of pulse width modulated (PWM) signal generator includes a module or modules to calculate an amount of change in a period length and duty ratio of an output signal during a transition period between a first signal waveform and a second signal waveform using a first period parameter, a second period parameter, and a parameter indicating a predetermined number of steps in the transition period. The period parameter and duty parameter of the output signal during the steps of the transition period are based on the calculated amounts of change.
