Step-by-step explanation:
A ripple counter counts sequentially through a series of states based on clock input pulses.
In the case of a MOD-15 ripple counter, it will cycle through 15 different states before repeating the sequence. Each state change occurs on every clock pulse.
To determine the output frequency, we can use the formula:
Output frequency = Clock frequency / MOD value
Given:
Clock frequency = 30 kHz
MOD value = 15
Plugging in the values:
Output frequency = 30 kHz / 15
= 2 kHz
Therefore, the output frequency of the MOD-15 ripple counter would be 2 kHz.
