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.
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 M5 Hz is not within soothing
hearing limits, take frequency, f =400Hz. Choose the capacitor value from the given list based on
the suitability of your requirements. (C = 50uF/250uF/470uF)
ii. What the advantages and disadvantages of the developed system for different stakeholders.
