Principles of Electronic Communication Systems

An amplifier has a gain of 45,000, which is too much for the application. With an input voltage of 20 µV, what attenuation factor is needed to keep the output voltage from exceeding 100 mV? Let $A_1$ = amplifier gain = 45,000; $A_2$ = attenuation factor; $A_T$ = total gain.
