A single-phase inverter is fed from a $\text{100 V}$ dc source and is controlled using a

quasi-square wave modulation scheme to produce an output waveform, $\nu\left ( t \right )$, as

shown. The angle $\sigma$ is adjusted to entirely eliminate the $3^{rd}$ harmonic component

from the output voltage. Under this condition, for $\nu\left ( t \right )$, the magnitude of the $5^{th}$

harmonic component as a percentage of the magnitude of the fundamental

component is _____________ (rounded off to $2$ decimal places).
