Is there an IC that can measure the phase of a sinusoidal current? For example, the US mains is a 120V, 60Hz sine voltage. The phase of the sine voltage is known as the sine voltage is generated by the power station. However, the phase of the current in the mains is unknown as the current is load dependent (the load can vary with the time). Is there a commercially available IC that can measure the phase of the sine current. The ac current may consist of a main frequency component and some harmonics. I am only interested in the main frequency component. Thanks in advance for any suggestion or advice.
尼玛不要成天弄些理论值好不好,你那东西64 byte就放不放得下就是个问题。还有你 的CPU一点开销都没有?10万/秒个请求,你的CPU能一点延迟没有处理得了?还是那句 话,你benchmark一个给大家看看,能达到那2万刀的机器我出了。你前面还怯生生得谈 1000 tps,现在就拿这数据死撑,真不要脸呀。 . The performance numbers were achieved utilizing single threaded, single queue depth 64 byte writes to the Auto-Commit Memory log.
