If the wave being sent is transmitted via an electromagnetic wave explain how the digital signal would be perceived if the signal was sent using: - Amplitude modulation
&
- Frequency modulation

Will mark brainliest, plz help.

amplitude is commonly for transmitting messages with a radio carrier wave, the amplitude (signal strength) of the carrier wave is varied in proportion to that of the message signal. at the receiving end, the message signal is extracted from the modulated carrier by demodulation. frequency is the encoding of information in a carrier wave with instantaneous frequency. with digital data, the frequency of the carrier is shifted among a set of frequencies, using digits like 1 and 0

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
