2) Sketch the Nyqpoiet plot by hand Sor the following systeon, choosing the contour to be to the right of the singularity the jwn axis Nert , wsing on the Nuquist criterion determine the mge of K z0 for which the sustemn is sca ble. Then, redo the Nuguist plot, this time Choosing the contour to be to the left of the imaryi mary the singularity avris. Again; on Osing Phe Ny quist criterion check the of Kz0 for which the sustem is range stable. Are the conswers the same? Should then be K G(s) = R Csra)
