RECEIVING DEVICE AND TIRE PRESSURE MONITORING SYSTEM
First Claim
1. A receiving device comprising:
- a receiving unit that receives encoded data encoded with a Manchester code in which a plurality of pulses comprising a high pulse and a low pulse are combined with each other so as to represent a bit;
a measuring unit that measures a pulse width of the pulses in the encoded data;
an edge determining unit that determines direction of an edge of an end of the pulse which is rising or falling, and a logical value determining unit that determines a bit data of the encoded data on the basis of the pulse width of the pulse, the direction of the edge of the end of the pulse, and a bit data of a bit before the determined bit, wherein when the edge of the end of the pulse is detected newly, the logical value determining unit determines whether the pulse is a pulse having length of 1 bit or a pulse having length of ½
bit, and determines whether the edge of the end of the pulses is positioned at a center of the determining bit or at a boundary between bits, then determines the bit data of the determining bit.

Abstract
A receiving device is provided. A pulse width is measured, it is selected whether a determination process is performed for a pulse width having the length of one bit in accordance with the measured value of the pulse width or a pulse width having the length of ½ bit, it is discriminated whether a current pulse edge is a pulse edge at the center of the bit or a pulse edge at the boundary between bits while considering the bit data right before the determined bit, and when it is determined that the current pulse edge is the pulse edge at the center of the bit, the bit data is determined by the rising edge or the falling edge of the pulse edge.
