Hello,
I’m starting in telecommunications, and teachers does not cease to repeat the word “frequency”, I know that F = 1 / T, so what’s the difference between a wave with a frequency of 100 kHz and another wave of frequency 4 kHz, and how an transmitter antenna can generate a wave of 100 kHz and another transmitter generate a wave of 4 kHz, and the same goes for the receivers how they make the difference between the frequencies??
Thank you in advance for your answers.
