Abstract: In the pitch searching method of the voice signal at the voice signal coding process by the vocoder, the method comprises the steps of: detecting the positive interval of the correlation which is high self-correlation among pitch relay values of the mixed signal from the remained signal of the voice signal, selecting the pitch searching interval, and excluding a negative interval of the remained correlation from the pitch searching interval by using symmetrical characteristics of the self correlation.

Abstract: when the content of an IR block is a repeated command word, asserting a command word "load-baf"; inputting a command word "Count-org" to a counter buffer, the command word "RE-org" to a RE buffer, and another command word "RS-org" to a RS buffer; if the repeated command word is one, asserting a command word "dec-cb" to thereby reduce the content of the counter buffer by 1; asserting the command word "freeze-pc" to thereby avoid a fact that the content of the PC is updated; asserting the other command word "load-rs" in case of fetching the command word to thereby transfer the command word to the counter block, the RE block, and the RS block, respectively; in case that the last command word is fetched, asserting the command word "load-rs" to thereby load the RS block in the PC block; and asserting a command word "dec-c" to thereby reduce the content of the counter block.

Abstract translation: 当IR块的内容是重复命令字时，断言命令字“load-baf”; 向计数器缓冲器输入命令字“Count-org”，向RE缓冲器输入命令字“RE-org”，向RS缓冲器输入另一命令字“RS-org” 如果重复命令字为1，则断言命令字“dec-cb”，从而将计数器缓冲器的内容减少1; 断言命令字“freeze-pc”，从而避免更新PC内容的事实; 在提取命令字的情况下，断定另一个命令字“load-rs”，从而分别将命令字传送到计数器块，RE块和RS块; 在获取最后一个命令字的情况下，断言命令字“load-rs”，从而将PC块中的RS块加载; 并且断言命令字“dec-c”，从而减少计数器块的内容。
