Double-sideband Suppressed-carrier Transmission - Generation

Generation

DSB-SC is generated by a mixer. This consists of a message signal combined with the frequency carrier.

\underbrace{V_m \cos \left( \omega_m t \right)}_{\mbox{Audio}} \times \underbrace{V_c \cos \left( \omega_c t \right)}_{\mbox{Carrier}} = \frac{V_m V_c}{2} \left[ \underbrace{\cos\left(\left( \omega_c + \omega_m \right)t\right)}_{\mbox{USB}} + \underbrace{\cos\left(\left( \omega_c - \omega_m \right)t\right)}_{\mbox{LSB}} \right]

Famous quotes containing the word generation:

    “Could it be that those who were reared in the postwar years really were spoiled, as we used to hear? Did a child-centered generation, raised in depression and war, produce a self-centered generation that resents children and parenthood?”
    —C. John Sommerville (20th century)

    “They shall beget and rear children, handing on the torch of life from one generation to another.”
    —Plato (c. 427–347 B.C.)

    “One generation abandons the enterprises of another like stranded vessels.”
