What Does Frequency-Shift Keying Mean? Frequency-shift keying (FSK) allows digital information to be transmitted by changes or shifts in the frequency of a carrier signal, most commonly an analog carrier sine wave. There are two binary states in a signal, zero (0) and one (1), each of ...
What does Coffey mean, by saying 'Education can be 'a proxy for many things''?语义题。proxy是代理的意思，从这句话所在的上下文，我们可以看出，首先Coffey指出教育并不是影响大脑容量的决定性因素，所以排除A。选项B和D虽然说法无误，但只是细节性内容，不是作者的主要观点。

I know I contribute to thiswhite noise, but I like to think I have theeducation, background, and evidence-based research to support any claims I make. When people make scientific claims, without substantial evidence to back them up, I get a littleskjfsljfsk…if you know what I mean…no...
Other modulation formats include frequency shift keying (FSK), phase shift keying (PSK), etc. It is important to remember when asking “What is LoRa?” that LoRa itself does not describe system functionality above the physical (RF medium) layer.The...

This tone is called 2-ary FSK, which denotes two frequency symbols. M-ary FSK has multiple frequency tones and can represent even more symbols. LoRa has taken this concept, but it does everything on a chirp. So, it is getting processing gain. Because it has a very distinct pattern, ...
There are some caveats to this calculation, but it should give them the confidence that they have plenty of money invested for retirement and that, if they’re willing to reduce their spending, Jane doesn’t need to go back to work (and neither does Joe!). ...
“And afterward he does not make any big production about it,” I said. “He just goes on reporting.” “It was not a rational time, not a conscious time,” Kolonitsky said. “Reed did not speak much Russian and what surrounded him often was simply chaos.” ...
normally uses peaks to copy the information needed. So does JT65. In the CW/SSB world we normally say "You were peaking RST 519"! K1JT has chosen to talk about an average signal level, which by definition is always going to be lower that the peak value that the program uses to copy...
