1.C.4 Amplitude Modulation with Large Carrier (AM-LC):
Modulation Index and Over-modulation
Consider a message signal m(t) that has a maximum value of Mmax, minimum value of
- Mmax and its AM-LC modulated signal:
g(t) = A (1+ kam(t)) cos(2nfct)
m(t)
Mm
= Ac 1 + μ
μ = kaMmax

1.C.5 Amplitude Modulation with Large Carrier (AM-LC):
Single Tone Modulation and Modulation Index
AM-LC modulation of single tone signals are used in radio navigation aids etc and also provides a
frame of reference.
Avionics & Comms
For a single tone message with amplitude Am, i.e. m(t) = Am cos(2nfmt), the AM-LC modulated
index is
g(t) = Ac(1+ kaAm cos(2nfmt)) cos(2лfct)
= Ac(1 + μ cos (2πfmt)) cos(2nfct)
μ = kaAm
