1. Realize signal modulation and demodulation functions, including various types of modulation such as ASK (amplitude modulation), PSK (phase modulation), FSK (FM). 实现信号的调制解调功能,包括各类调制如ASK(调幅),PSK(调相),FSK(调频)。
2. Single-phase APF(Active Power Filter) with one-cycle control has two modulation methods-bipolar modulation and unipolar modulation. 单周控制单相有源电力滤波器(APF)有双极调制和单极调制2种调制方式。
3. The phase speciations of trace thallium in the Yunfu pyrite ore are analyzed, including exchange phase, carbonate phase, oxide phase organic, sulfide phase and phase combined with quartz etc. 分析了云浮硫铁矿中微量铊的相态分布,包括可交换相,碳酸盐结合相,铁锰氧化物结合相,有机质及硫化物结合相,硅酸盐结合相等相态。
4. The objective of automatic modulation identification is to decide the modulation type and estimate the modulation parameters without any prior knowledge about the signal information content. 调制识别的目的就是在未知调制信息内容的前提下,判断出通信信号的调制方式。
5. Measure to receiver, HP8644A can provide amplitude modulation, frequency modulation and pulse modulation signal. 对于领受机测量,HP8644A可供给调幅、调频和脉冲调制信号。
