Frequency Division Using Dual Modulus Prescaler

Open the model Dual_Modulus_Prescaler_Ex. The model consists of a Pulse Generator and a Dual Modulus Prescaler block.


The period of the incoming pulse at the clk in port is 1e-7 s. So, the incoming signal has a frequency of 10 MHz. The Program counter value, Prescaler divider value, and Swallow counter value are 4, 1, and 1, respectively. The effective clock divider value of the dual modulus prescaler is 5.

Run the simulation for 1e-4 s. The frequency of the output signal is 2.002 MHz.
