Find the correct match between group 1 & group 2 Group
P. (1+km(t)A sin(\Omega t))
Q. km(t) A sin(\Omega t)
R. A sin(\Omega t + k m(t))
S. A sin[\Omega t + k \int (m(t))]
Group 2
W. Phase Modulation
X. Frequency Modulation
Y. Amplitude Modulation
Z. DSB-SC Modulation
(a) P-Y , Q- Z , R- W, S-X
(b) P-Z , Q -Y, R - W, S- X
(c) P- X, Q-W,R-Y,S-Z
(d) none of above
Answer is ( a )
Concept
(1+km(t)A sin(\Omega t)) - Amplitude Modulationkm(t) A sin(\Omega t) - DSB-SC Modulation
A sin(\Omega t + k m(t)) - Phase Modulation
A sin[\Omega t + k \int (m(t))] - Frequency Modulation
