Round 1

Reviewer 1 Report

1. The triplen harmonics most savior harmonics shown by 3(2N+1), where N=0, 1, 2…., i.e. 3, 9, 15, 21, etc. the triplen harmonics have zero sequence nature and it accumulates as neutral current. - Please comment on this

2. The balance harmonics Equation is not clear.

3.  proposed method can achieve -46.24dBc and -54.05dBc respectively when the coding efficiency 18 reaches 77.51%. No proper Proof in the results session

4. Introduction is very weak 

5. Please add the relevant reference paper - Recent references 

6. Experimentation results need to be validated even better

Reviewer 2 Report

A 5-level RF-PWM method with third and fifth harmonic elimination for all-digital transmitters is proposed in this manuscript, which can help to realize the efficient power amplication. The core idea is interesting and well analyzed. But there is a minor mistake that some symbols are not difined, such as Vth1(t) to Vthn, and U in Fig. 4.
