Cvsd ( continuous variable slope delta modulation ) voice coding enables operation at high bit - error rates 连续可变斜率增量调制的语音编码可以在高误码率的情况下正常工作。
The results indicate that sigma delta modulation could improve spurs of fractional - n frequency synthesizer in a certain extent 研究表明, -调制技术可以在一定程度改善小数分频的杂散。
And the record / playback 1c , using one - bit delta modulation ( adm ) , has been designed and made widely for its simple production and feasibility 而采用adm (自适应增量调制)编码的语音录放专用芯片因其简单实用而被广泛研制。
Further more , a delta modulation ( dm ) is given for the unique structures by researching rdcli ’ s control strategies 然后,进一步研究谐振直流环节逆变器的控制策略,针对这一独特的拓扑,提出了用delta调制技术作为其控制策略。
