Questions 1-5 on D-Latch are based on the timing diagram given below. In the diagram, time interval refers to the window of time between two vertical dashed lines. Each interval has a letter name used to refer to it in the questions. When CLK 1. During interval A, the output QD-Latch is a. Always zero b. Always one c. In upward transition, L.e. changing from zero to one d. In downward transition, i.e. changing from one to zero 2. During interval B, the output Qp-Lath is a. Always zero b. Always one c. In upward transition, i.e. changing from zero to one d. In downward transition, i.e. changing from one to zero 3. During interval C, the output Qp-Latch is a. Always zero b. Always one c. In upward transition, i.e. changing from zero to one d. In downward transition, i.e. changing from one to zero . During interval D, the output Qp-Latch is a. Always zero b. Always one c. In upward transition, i.e.changing from zero to one d. In downward transition, e. changing from one to zero 5. During interval E, the output Qp-Latch is a. Always zero b. Always one c. In upward transition, i.e. changing from zero to one d. In downward transition, i.e. changing from one to zero
