Chapter 1313 The Infore (2/2)
If the culprit who murdered him was still alive by then, they would not escape severe punishale nodded ”If only we can quickly create the communications equipment that extends over thousands of miles that you spoke of”
”Unfortunately that is not one of ths” Roland couldn't help but rub his forehead Recalling the circuit diagram that he had been forced to memorize s during an exaale said with her hand to her mouth
”Hard as it is, I'm at the very l east not like a certain someone who simply falls asleep on the table and hands in an elared at her ”I've actually alh extremely slow, the radio coine, after considering nun Bureau of Graycastle, he decided to select two a them and have theap transap transn was extremely simple and didn't need any electronic components All that was needed was a transfore the capacitor until the voltage in the capacitor was large enough to ionize the air and produce an electric spark This part was sied by the spark would not be wasted and instead, would oscillate rapidly back and forth between the plates of the capacitor through the inductor and spark gap, creating electronetic waves would be trans as one could control the switch of the power source, internetic waves could be sent out, and by listening to the duration of the sounds, receivers could translate theths of telegraph codes originated froh it still sounded a little confusing, Roland took the enious approach, which was to have the radio con Bureau of Graycastle to build a machine that worked with readily available materials, and then copy it
For example, if you place a piece of oiled paper between two pieces of tin foil and then seal it ax, it becoe capacitor
The inductor would be even easier tomore than a coil of ound round and round an insulated pipe
When not taking mass production or specifications into consideration, Roland could coh coe the size of a fingernail in his previous life, these devices would appear bulky and crude, but the effects were basically the same After the construction of the launch toas completed, he would be able to perfor experiap transmitter were also very obvious
Even if it passed the trials, he would have to design a code that do senders and receivers would also require a lot of tiap transmitter had an extremely wide frequency spectruion It wasn't suitable for the intelligence personnel to use on the frontlines
Thus, his ultioal was still to use an amplitude-nal using a vacuue of the AM transnals
In principle, radio and telephones were very similar in nature Both transfores in current or electro distances to the receiver's location, it would be turned back into sound oncewas that the frequency of the hunal wave to be too long The longer the wavelength, the larger the required antenna size—if the voice signals were directly transth of the antenna would be over a hundred kilo impossible to create with their construction capabilities
So in order to send out the voice signal, it would have to be carried by a higher-frequency wave
This here 'modulation' came in
Once the neave form created by the combination of the tas received, the receiver had to filter out the high-frequency waves through a series of deful low-frequency waves in order to turn it into the final sound of the voice
Once the AM transence coranted with real-tinificance of this required no explanation
