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.
Usually high frequency sine wave is used as a carrier wave signal. These modulation techniques are classified into two major types: analog and digital or pulse modulation. Prior to discussing further about the different types of modulation techniques, let us understand the importance of modulation. Why modulation is used in communication? Need of Modulation
