39. From a given transfer function- which quantities do not depend on the system gain- a.) Peak time, b.) Rise time, c.) damping ratio, d.)----
HAL Questions given from the Reasoning section were average. From the technical Section questions lie between the PSU level and the Gate Level. Will post other question if I could Recall
Best of Luck to all the candidates
