Description

Attach the DRMS block to a signal to compute its discrete-time, cumulative root mean square value. Use in conjunction with the Signal Constraint block to optimize the signal energy.

The discrete-time, cumulative root mean square value of a signal u(t_i) is defined as

$$R.M.S=\sqrt{\frac{1}{N}{\displaystyle \sum _{i=1}^N{\Vert u(t_i)\Vert }^2}}$$

The R.M.S value gives a measure of the average energy in the signal.
