# What does this bandpass signal equation indicates?

This is the equation for bandpass signal from transmitter. What are the values for different parameters present in this equation. For example, what should be the value of P, Sl(t), Fc etc. Also what is the meaning of j in this equation.

Source for context.

• Don't think the answer is already present in the image. Example $f_{c}$ is center frequency – Mahendra Gunawardena Sep 11 '19 at 10:43
• Thanks for reply@ Mahendra , but what is the value for average transmitted power and Sl(t). – charu Sep 11 '19 at 11:44
• @mahendra I think Sl(t) will also have some equation. – charu Sep 11 '19 at 11:45
• @charu, I suggest the you use LaTex format to improve readability for symbols such as $\rho$ – user8055 Sep 11 '19 at 13:36
• @user8055 sure ....from next time I will incorporate this. – charu Sep 12 '19 at 14:32
