Design a wideband band-pass active filter that has a gain of 17dB in the passbandand has corner frequencies at the lower and higher frequency limits of human hearing (i. e. 20Hz to 20kHz).

Solution :

A wide band pass filter has (Q < 10)

Gain in dB of overall filter = 17 dB

Let

Since the overall gain off filter is 5.47

the correct answer is c.stops after infancy and childhood.

myelin is the substance of the central nervous system (cns) that insulates nerve cell axons to increase the speed at which nerve impulse travels. myelination is a process of myelin formation. this process occurs postnatally, begins in the embryo during the midst of early development and finishes after birth.
