SUMMARY

Pulse Amplitude Modulation (PAM) is not suitable for long-distance transmission due to its susceptibility to noise and signal degradation over extended distances. The infinite length of the output signal contributes to these issues, making PAM less effective compared to other modulation techniques. This discussion highlights the limitations of PAM in the context of applied electromagnetics and transmission line theory.

PREREQUISITES
  • Understanding of Pulse Amplitude Modulation (PAM)
  • Basic principles of digital communication
  • Knowledge of noise impact on signal transmission
  • Familiarity with transmission line theory
NEXT STEPS
  • Research alternative modulation techniques such as Quadrature Amplitude Modulation (QAM)
  • Explore noise reduction techniques in digital communication
  • Study the effects of signal degradation over long distances
  • Learn about transmission line theory and its applications in communication systems
USEFUL FOR

Students and professionals in applied electromagnetics, digital communication engineers, and anyone interested in understanding the limitations of modulation techniques like PAM in long-distance transmission scenarios.

Homework Statement



Just came across the statement that PAM is not very good for long-distance transmission.
Why is it so?
Thanks.

Homework Equations

The Attempt at a Solution



Is it because the output is of infinite length?

what the heck is pam and what class is this for? (is it for applied electromagnetics with an intro to transmission line theory?)

Ops.

PAM = pulse amplitude modulation
for digital communication.
