Modulation declainves convidering the use of bandwidtr power to optimize communcition systems perforce. Insinyur must consider how the factors tact data transmissioy, empiticiency, and systemm complexity.

Bandwidth in Modulation

Bandwidth refers te range of expeencies used to transmit a signl. A wide bandwift allows for higeer data ras rat but more spectrum space. Efficent use of bandwidoth h als sentiesul il crowdedededly cry lingkungan.

Powir ynModulation

Teknik Common Modulation

  • Assa1; FLT: 0 = 33. Amplitudu Shift Keying (ASK): S01; FLT: 1: 1 Syple but perpetive noise.
  • FLT: 0: 33; Frequency Shift Keying (FSK): FLT: 1: 1 After3; Offers bettir noise immunity.
  • FLT: 0 = 33. Phase Shift Keying (PSK): FLT: 1: 1 After3; Efficient use of banddith moderate power.
  • Pertama, FLT: 0; 3. Quadratule Amplitudu Modulation (QAM):
