设计遥控器接收解码电路。该电路接收编码后的串行数据，解码输出数据。电路接收
到的串行数据的格式为： 4 位同步码“ 1010”， 4 位数据（高位在前）， 1 位奇校验码（对前 8 位数据校验）(Design of remote control receiver decoding circuit. The circuit receives the encoded serial data and decodes the output data. The format of the serial data received by the circuit is: 4 bit synchronous code "1010", 4 bit data (high in the front), 1 bit parity check code (check for the first 8 bits of data))
