Title:
位相検出器及び位相検出方法
Document Type and Number:
Japanese Patent JP2007505327
Kind Code:
A
Abstract:
In order to provide a phase detector and a method of phase detection which are distinguished by greater sensitivity and simple implementability, at least one differential signal of two input signals (Ua; Ub) may be formed over at least one predefined period by means of a first subtracter ( 12 ), at least one maximum value of the at least one differential signal may be detected by means of a first peak detector ( 16 ) and at least one minimum value of the at least one differential signal may be detected by means of a second peak detector ( 18 ) and at least one further differential signal (Uout) may be formed from the at least one maximum value and the at least one minimum value by means of a second subtracter ( 14 ).
