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]](http://upload.wikimedia.org/math/a/a/1/aa16f4fd9725d0f47f4405d0d661c624.png)

Famous quotes containing the word generation:
“This generation has come into the world fatally late for some enterprises. Go where we will on the surface of things, men have been there before us.... But the lives of men, though more extended laterally in their range, are still as shallow as ever.”
—Henry David Thoreau (1817–1862)
“The greatest significance of the present student generation is that it is through them that the point of view of the subjugated is finally and inexorably being expressed.”
—James Baldwin (1924–1987)
“Once I prophesied that this generation of Americans had a rendezvous with destiny. That prophecy now comes true. To us much is given; more is expected. This generation will nobly save or mainly lose the last best hope of earth. The way is plain, peaceful, generous just. A way, which if followed, the world will forever applaud, and God must forever bless.”
—Franklin D. Roosevelt (1882–1945)
