Changing the phase encoded direction had little to do with the accuracy of FA value.

相位编码方向对成图的质量及数值的准确性方面贡献不大。

There are four possible phase shifts, allowing two bits of data to be encoded per symbol.

因为相位偏移有四种可能，所以每一个符码可以对两比特位的数据进行编码。

The researchers also found information could be encoded depending on the phase - or timing of the brainwave - and less so by its amplitude - or strength.

研究人员还发现，根据相位信息可以被编码- 或脑电波的时间 – 而较少受到其振幅或强度的影响。
