represents an upper-sideband signal with no spectral components below the carrier angular frequencyωc, wheres(t) is an arbitrary message function and σ(t) its harmonic conjugate. This equation can be written in the form es(t)=[s2(t)+σ2(t)]1/2cos{ωct+tan−1[σ(t)/s(t)]}=α...
The RMS value is, in either case 〈x2〉. For analytical description, the variance is given by: (10.17)σx2 = ∫-∞∞(x - 〈x〉)2 p(x)dx The discrete form is given by substituting a summation for the integral and δx for dx. Equation (10.17) can be simplified as ...
