- You can check the following documentation for more details on this :https://www.mathworks.com/help/simrf/ug/power-in-simulink-sources-and-signals.html#d123e16001
- The Amplifier block only accepts a vector input. The Sum block combines the two baseband signals into a vector length equal to the samples per frame in the DSP Sine Wave block.

Hello everyone,
I am learning on the RF blockset on how to use this block properly.
After read through this example documentation. I have some question on this.
1) How the amplitude of 2 baseband tone is exactly -20 and -25 dBm respectively?
On that block it using 10^((-20-30)/20) for -20 dBm amplitude and 10^((-25-30)/20) for -25 dBm.
What is the fomular that being used?
2) What is the purpose of "Sum" block in this example?
