One operational amplifier with a frequency range of (18-20) MHz has
input resistance 10 kohm. Calculate noise voltage at the input if the
amplifier operate at ambient temperature of 270C.
Vn
2 = 4KTBR

4 x 1.38 x 10-23 x (273+ 27) x 2 x 106 x 104

Vn = 18uvolt

1) draw bessel table
2) draw frequency spectrum
