Pcm sound recording and reproducing device
专利汇可以提供Pcm sound recording and reproducing device专利检索，专利查询，专利分析的服务。并且PURPOSE:To perform high-precision IC-implementation, by providing a means of generating a compensation state signal to the error compensating circuit of an AD and a DA converter. CONSTITUTION:For example, when play music is recorded on a recording medium 1, the means of generating the compensation start signal 2 detects recording contents being silence for a time T necessary for compensation between pieces of play music or in play music and makes the compensation in this nonmusic period. A shift register 23' is a partial circuit of a signal processing part 23 and stored with a digital sound signal in the compensation period T. A digital comparator 41 detects silence. A shift register 42 is stored with comparison results for the compensation period and an AND circuit 43 outputs the compensation start signal 2 when detecting the continuation of silence for the compensation period T. In this constitution, when the nonsound period is as long as the period T, the AND circuit 43 outputs a signal with a level ''1'', which is used as the compensation start signal. The compensation start signal 5 for a sound recording system is obtained associatively with a power source switch, etc.，下面是Pcm sound recording and reproducing device专利的具体信息内容。
