A noninverting op-amp circuit with a gain of 96 V/V is found to have a 3-dB frequency of 8 kHz. For a particular system applicat
umka21 [38]

Answer:

Av_2 =24\ V/V

Explanation:

given,

op-amp circuit with a gain of = (Av₁) = 96 V/V

Band width  = (Bw₁) = 8 kHz

Required bandwidth(Bw₂) = 32 kHz

Highest gain available =(Av₂) = ?

For the given system Bandwidth product is constant

                           Av₁ Bw₁ = Av₂ Bw₂

                           96 x 8 = Av₂ x 32

                           Av_2= \dfrac{96\times 8}{32}

                           Av_2 =24\ V/V

the highest gain available under these conditions Av_2 =24\ V/V

Two students designed an experiment to study the effect of solar radiations on four cities of Earth. They used a globe to repres
Furkat [3]
Great experiment !  Everybody should try it if they can get the equipment. 
It demonstrates a lot of things that are very hard to explain in words. 

I hope the students remembered to tilt the axis of the globe.  If they didn't,
and instead kept it straight up and down, then each city had pretty much
the same amount of bulb-light all the way around, and there were no seasons.

If the axis of the globe was tilted, then City-D had the least variation in
seasons.  City-D is only 2° from the equator, so the sun is more direct
there all year around than it is at any of the others.
