I. Outline the necessary steps in correct sequence of the standard procedure to design a digital system

Fantastic news! We've Found the answer you've been seeking!

I. Outline the necessary steps in correct sequence of the standard procedure to design a digital system and design the system. Also show the outlined steps, which will trigger the alarm and implement the system with CMOS logic.
ii. The human audible ranges from 20Hz – 20kHz. However, any sound below 250Hz is considered to be disturbingly low pitched and any sound above 4500Hz is considered to be disturbingly high pitched.
Design the alarm timer circuit with a frequency of P5 Hz and a duty cycle of Q% [where P= C+O+V+I+D and Q = 100 – P].
However, if P5 Hz is not within soothing hearing limits, take frequency, f =400Hz.
Choose the capacitor value based on the suitability of your requirements. (C = 50uF/250uF/470uF)
iii. Identify the limitations of this developed system and explain the effect of increasing the frequency above 4500Hz
