Design Problem: 1. You are asked to design a frequency divider (f/2 where f is the clock frequency) using 74LS74 D flip flop IC. 2. For your convenience schematic diagram and trimming for the divide by 2 flip flop is given. D Q f/2 CLK CLK Q k f/2 Duty cycle of 50% (ON-1, OFF-1) Figure 2: Divide by two counter 3. You need to set up the circuit as shown in the figure 2 by using the 74LS74 IC package and the pin diagram for the 74LS74 is given in figure 3.
