Can you solve this question?
Question 2. (18 points) The transfer function of a so called Gaussian lowpass filter-amplifier is given by: -=4e-af²f d) Your (f) H(ƒ)=- Vin (f) with a = 5.10-s. Further it is given that fe -ax² 0 1 dx == for a > 0. a) Calculate the -60 dB bounded bandwidth of this filter-amplifier. b) Explain in your own words the meaning of "equivalent noise bandwidth", and why is this a usefull parameter? Calculate the equivalent noise bandwidth of this filter-amplifier. At the input of this filter-amplifier, a sinewave signal s(t) = 2 sin 200nt and additive white Gaussian noise with a double-sided power spectral density N₁ = 5.10-7 V²/Hz, are present. Calculate the signal-to-noise ratio (SNR) of the sinewave signal at the output of the filter-amplifier.
