C. Triplet components
D. None of the mentioned
Answer:A
In the relation, the low frequency components uc and us are called __ of the bandpass signal x(t).
A. Quadratic components B. Quadrature components C. Triplet components D. None of the mentioned
Explanation: The low -frequency signal components uc(t) and us(t) can be viewed as amplitude modulations impressed on the carrier components cos2πFct and sin2πFct , respectively. Since these carrier components are in phase quadrature, uc(t) and us(t) are called the Quadrature components of the bandpass signal x (t).
