You should eat a light and healthy meal before you are supposed to begin fasting prior to surgery. Avoid heavy foods with a lot of unhealthy fats, as they take a long time to digest; for example, loading up on pizza the night before an operation is not a good idea.
Amplitude modulation compared to Pulse position modulation'?   Amplitude modulation (AM) is a technique used in electronic communication, most commonly for transmitting information via a radio carrier wave. AM works by varying the sâ¦trength of the transmitted signal in relation to the information being sent.
Phase modulation (PM), in which the frequency of the carrier waveform is varied to reflect changes in the frequency of the data (similar but not the same as FM). Polarization modulation, in which the angle of rotation of an optical carrier signal is varied to reflect transmitted data.
