The number of turns per second is the frequency of the light. Now take another path; it has, for instance, a different time, so the vector for it is turned through a different angle—the angle being always proportional to the time. Take all the available paths and add on a little ...
a return to equilibrium, then a negative variation, and return to equilibrium. This relationship is often described in terms of the sine wave, and the frequency referred to is that of an equivalent sine-wave variation in the parameter under discussion.SeeFrequency measurement,Sine wave,Wave motion...
We study the instantaneous frequency of a signal which is formed by the summation of a sinewave and a bandlimited signal. We refer to the composite signal as a sinewave squelched or simply a squelched signal. We study the behavior of the squelched signal at its real zeros and extrema. ...

Output signals of the FF 13 and the phase shifter 15 are brought to a frequency division by the FF 14 and 17, respectively. In this way, when the sine wave signal iA of a prescribed amplitude is outputted from the generator 1... N Tadamasa,K Shigenori,K Kazuo,... 被引量: 0发表...
事实是:在自然界中,没有一次只以一个频率(frequency)振动的声音。 一个只以一个频率振动的声音是正弦波(sine wave),这就是只有一个频率听起来的样子。 任何其他的声音事实上总是由很多频率组成的混合物。 其中,较低的频率被称为基音(fundamental,或称为基波)——这往往是我们听到而且能唱的音符,其他所有的频率...
