How to convert analog signals to digital |
| abstract |
(57) [Summary] The present invention provides a first output signal sin θ− at the preceding stage of a control deviation ε when obtaining sin (θ−φ) as a control deviation ε. Most of them are converted into digital circuits by converting (φ) ・ f (t) into digital signals based on the sign of the comparator. It is an object of the present invention to provide a method of converting an analog signal into a digital signal which is easily integrated into an IC. A method for converting an analog signal into a digital signal according to the present invention uses a comparator (200) that introduces a rotation detection signal into a multiplier (200) and calculates sin (θ−φ) · f (t). This is a method of making a stable and inexpensive configuration by converting into a digital signal by the positive / negative determination according to 54). |
