专利汇可以提供Mixing system in delta m time division exchange专利检索,专利查询,专利分析的服务。并且PURPOSE:To realize a mixing system in a delta M time division exchange flexible for increment and reduction of the number of subscribers by mixing voice, etc., of plural subscribers without a mixing trunk. CONSTITUTION:Input signals enter delta M coder MCD from subscribers A and B, and each digitized signal enters highway switch HWSW. Flip flops FF in MCD have the phase shifted by the half period, and in delta M decorder DEC, these flip flops are caused to generate clocks alternately only in the half of one frame as clocks of FF, thereby generating delta M signal A+B from delta M signal A and delta M signal B. This signal is transmitted to C as demodulated signal A+B through integrator INT. Then, it is sufficient if positions of time slots are shifted by 1/3 or 1/4 in case of increment of the number of subscribers, and and as a result, this system is so flexible as to cope with increment and reduction of the number of subscribers in pulse technique.,下面是Mixing system in delta m time division exchange专利的具体信息内容。
