假设在一个数字通信系统中,BER要求为1e-6(即每传输1百万比特中最多只能出现1个误码)。我们可以利用上述换算公式来计算对应的SNR值。 SNR = 10log10(1/1e-6) ≈ 60 dB 所以,要满足BER为1e-6的要求,信噪比至少需要达到60 dB。 这个例子说明了BER换算SNR公式的应用。通过这个公式,我们可以根据对传输质量的...
当前鲜见表征过敏原蛋白Ber e 1三级结构的报道,因此本研究为过敏原蛋白Ber e 1的后续研究奠定了一定的基础。 7、巴西坚果过敏原Ber e 1的得率分析 如表2所示,在一次典型的纯化过程中,上样体积为6 mL,总蛋白质量浓度为26.0 mg/mL,获得纯化的Ber e 1约22.4 mg,计算可知,Ber e 1得率为47.8%,则1 g巴西...

Albinism is rare in this species, and the incidence rate of each age and sex cohort is not well known. Consequently, we examined the pigmentation of Mourning Doves encountered in the Coastal Plain of South Carolina, and classifi ed the age and sex of all individuals. One adult male......
An error is detected only if e(x) is not a multiple of g(x), in which case the remainder is zero: Equation 6 Figure 1shows a sequential circuit for calculating the remainder. The coefficients in the circuit are the polynomial coefficients for the generator polynomial g(x). The lowest- ...
