摘要： Provided is a wireless microphone system comprising a microphone and a wireless receiver, wherein the wireless microphone system is provided with: a normal communication mode in which communication is performed by using a normal unique word (UWN) preset in both the microphone and the wireless receiver devices; a confidential setting mode in which a confidential unique word (UWX) is transmitted without being set in either of said devices; and a confidential communication mode in which communication is performed by both said devices by using the confidential unique word (UWX) set by the confidential setting mode.

摘要： A master clock signal source (10) generates a master clock signal having a frequency equal to N times the bit rate of received data, where N is a positive integer. A modulo-N counter (12) counts the master clock signal. An edge detecting circuit (4) detects a transition of the received data from a H level to a L level. A counter (8) counts the master clock signal and resets the modulo-N counter (12) if the count counted during a time period in which three edge representative signals occur is 2N. In accordance with the count in the modulo-N counter 12, a clock generating unit 14 generates a clock signal.
摘要翻译：主时钟信号源（10）产生具有等于接收数据的比特率的N倍的频率的主时钟信号，其中N是正整数。模N计数器（12）对主时钟信号进行计数。边缘检测电路（4）检测从H电平到L电平的接收数据的转变。如果在发生三个边缘代表信号的时间段内计数的计数器为2N，则计数器（8）对主时钟信号进行计数并复位模N计数器（12）。根据模N计数器12中的计数，时钟产生单元14产生时钟信号。
