CW：可以说有两种意义，一种是连续波信号，实际上就是正弦波做载波，这样解释的话，CW可以包含线性调制（AM，DSB，SSB，VSB等）、非线性调制（FM、PM）、数字调制（ASK、FSK等）；另一种意义说的是等幅数据报或者等幅波电报，印象中业余无线电爱好者经验会用到，莫尔斯电码好像就是。那其中的AM信号...
如果用了CW可能会低估器件能力,要去选用一个功率比实际应用高上不少的器件,这个通常就是芯片面积增加或要选用更好的材料,最后导致成本上升….但用Pulse Mode如果挂了,造成项目延迟那年底不就汽车变摩托。 GMSK与Pulse Mode 这里补充一下锐石创芯RadRock有些规格书会用GMSK来测试验证,[6] GMSK的调制讯号是FSK的一...
EPROxychipThe goal of this work was to compare pO2measured using both continuous wave (CW) and pulse electron paramagnetic resonance (EPR) spectroscopy. The Oxychip particle spin probe enabled longitudinal monitoring of pO2in murine pancreatic tumor treated with gemcitabine during the course of ...
