But again, I'm not going to explain this to you nor do I have to. If you choose to be naive, that's your choice. Not mine... Most of the surveillance done on copper wire is done with Longitudinal Current. SOME is done with Metallic Current over plain old telephone service but not as much as it used to be.[/b]
I challenge you to describe how any type of signal would be able to run in the opposite direction against a DC current, survive a transformation into AC current... none of which is possible... and somehow do this without a modulator in the first place. That's not naivety... that's science.
I promise you... the NSA has much easier ways to spy on you.
You're so full of shit, dude. For someone who CLAIMS to be a damn electrical engineer, YOU DON"T KNOW SHIT. ESPECIALLY, About transmission. I'm not going to bother trying to explain it to you IN DETAIL because you want to PRETEND like you know what the hell you're talking about when you don't. You do NOT deserve my time.EXAMPLE OF MANY BELOW:
You do NOT even realize the telephone line is POWERED BY DC, dude. Do you? It's 48 to 52 Volts DC. However, when we talk it is AC. When you press buttons to dial out, those are Dual Tone Multiple Frequencies (DTMF Tones). Those tones are AC, Dude that's riding on the same damn two wires as the DC that's powering the circuit. That's only one example of MANY.
Do you not realize when we talk on the telephone line, it is AC but IT IS POWERED BY DC. Meaning, AC AND DC ARE BOTH ON THE SAME COMPONENTS (WIRE - COPPER).
YOU"RE FULL OF SHIT AND NOT WORTHY OF MY TIME. STOP PRETENDING LIKE YOU KNOW SOMETHING WHEN YOU DON"TYour precious DC current is powering even old rotary phones with 48 to 52 volts DC on the phone line. That's WHY you can still have dial tone with an old rotary phone when the power is out to your house. Well, that precious DC current of yours can be converted into AC current when you talk on the damn phone by an oscillator by varying the capacitance when your voice bounces off the diaphragm to change the distance between the metal in the diaphragm and the metal in the oscillator. Metal plates separated by an insulator is a capacitor. But BOTTOM LINE: AC is on the Tip and Ring WITH YOUR PRECIOUS DC THAT YOU SAID, "NONE OF WHICH IS POSSIBLE." Actually, you're full of shit and do not even know it.
I don't know why I'm even bothering wasting my time explaining this to you. You're a damn ass hole who wants to act like he knows every damn thing. I will tell you this: If I do not know something, I won't hesitate to tell you, "I DO NOT KNOW THAT" and I will NOT feel bad about not knowing it. I'll simply invest the time to get to know it if I feel it's worthy of my time to know it. That way, I avoid wasting someone else's time and I also avoid making a damn fool of myself; pretending I know something if I really don't.
I'm sure there are things you know that I don't know. Does that make you any smarter than me or I than you if I know something you don't? HELL NO.
So, STOP PRETENDING like you know something when you don't. IF YOU'RE NOT 100% SURE OF SOMETHING, YOU NEED TO AVOID MAKING A FLAT STATEMENT. Because it really doesn't look good if you're wrong. No?
