You can calculate power, entropy, and energy as features for these signals. Other than that, you can aslo try calculating slope, standard deviation and negative slope.

Thanks Jyotish !
I tried calculating power, entropy, STD, Variance , Mean and energy but these 2 signals couldn't be differentiated by these features.
Could you please let me know the formula to calculate the Slope using MATLAB.

go through this link to find slope. You can also calculate phase in order to distinguish these two signals.
