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）。解码电路检测到校验位正确后，输出数据及一个时钟周期的数据有效脉冲。如果校验位错误，则不输出数据，也不输出数据有效脉冲。画出状态转移图，标明各个状态的转移条件和输出-Design of remote control receiving and decoding circuit. The circuit receives the serial encoded data, decoding the output data. Circuit receives the serial data format:4 bit code"1010",4 bits of data ( high byte first),1odd parity code ( on the first 8bit data check ). Decoding circuit detects parity bit is correct, the output data and a clock cycle data valid pulse. If the parity bit error, no output data, or output data valid pulse. Draw a state diagram, mark each state transition and output
