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.
Pulse width modulation is used in a variety of applications particularly for control. You already know it can be used for the dimming of LEDs and controlling the angle of servo motors and now you can begin to explore other possible uses.
