Question

Solve this Problem, Sir.

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=
N+O+I+S+E and Q = 100 P]. However, if P5 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)
