I wonder about frequency wave..

Frequency is a wave and there are two type of frequency likely mekanical wave and electro wave, each of them are frequency form. For the electronic wave, it has been more than less century it used to establish activity of mankind. Such as telecomunication, mixer wave, radio etc

But utillize of frequency not only stop from that world, frequency also has developed to expanding use. Lately is sanding voltage. I can only think the frequancy also have opportunity to more develope again in furture time. Perhaps for human interface or robotic.

Now if we emphasize in telecomunication frequency is very outstanding cause trough voltage that we changed must be suit in flip flop condition. It can potential  to make wave and amplitude within of voltage. In addition the wave will be setted  by osillator particularly in this case we use handry law.

This osillator receive input trough microphone while it work. It’ll make a wave in a certain periode. DC current change positive and negative with assist of inductor become AC. The manner posible to be a tiger for a transistor. Pertending the transistor become switch on and off such a pulse.  So that this frequency can be heart we deed some device that we used for  gain and louder. Therefore we need opamp as gain and louder. But it still interfere to direct transmitte frequency . instead we need repeater before using  opamp as a gain and loud speaker.

Those are the complicated of the frequency world
