What is the expression for the modulation wave?
What is the expression for the modulation wave?
- $Vam(t)=20sin(2Ï€510kHzt)-3.75 cos(2Ï€510kHzt)+3.75 cos(2Ï€490kHzt)$
- $Vam(t)=20sin(2Ï€500kHzt)-3.75 cos(2Ï€510kHzt)+3.75 cos(2Ï€490kHzt)$ (correct)
- $Vam(t)=20sin(2Ï€510kHzt)-7.5 cos(2Ï€510kHzt)+7.5cos(2Ï€490kHzt)$
- $Vam(t)=20sin(2Ï€500kHzt)-3.75 cos(2Ï€490kHzt)+3.75 cos(2Ï€510kHzt)$
