By simply adjusting the frequency difference between the CW light and the carrier of the optical SSB signal, the frequency of the generated microwave SSB signal is changed correspondingly. In the experiment, amplitude shift keying (ASK) microwave signals with the SSB format are successfully generated...
抗SS-B抗体阳性并不一定是干燥综合症。干燥综合症的症状包括口腔和眼睛干燥，而抗SS-B抗体主要用于检测...
【数字信号调制】基于matlab GUI AM+DSB+SSB+ASK+FSK+PSK调制解调【含Matlab源码 058期】 一、获取代码方式 二、调制解调简介 1 绪论 调制:把消息信号寄托到载波的某个参数上,形成已调信号。 解调:调制的逆过程,从已调信号中恢复消息信号。 2 调制的目的...
抗SSB抗体弱阳性表示可能存在自身免疫性疾病,但弱阳性结果并不一定能确诊,需要结合临床症状及其他检查结果进行综合判断。 抗SSB抗体是一种自身抗体,主要见于系统性红斑狼疮、干燥综合征等自身免疫性疾病。当人体的免疫系统出现异常时,会产生针对自身细胞或组织的抗体,抗SSB抗体就是其中之一。如果检测出抗SSB抗体弱阳性,...

SSB抗体阳性有可能是干燥综合征,也有可能是其他免疫病,需要检查清楚之后,根据医生指导治疗。 SSB抗体阳性需高度警惕干燥综合征,不过为了更准确的确诊疾病,还需进一步了解有无口干、眼干、腮腺肿大等表现,同时还应完善唾液腺ECT、唇腺活检等检查。如确诊为干燥综合征,可在医生指导下使用环磷酰胺片、甲氨蝶呤片等药物治疗...
