সমাধান:

প্রথম পরিবর্ধকের লাভ, V 1 = 10

দ্বিতীয় অ্যামপ্লিফায়ারের লাভ, V 2 = 25

দুই-পর্যায়ের ক্যাসকেডেড এমপ্লিফায়ারের মোট ভোল্টেজ লাভ উভয় পর্যায়ের ভোল্টেজ লাভের গুণফল দ্বারা দেওয়া হয়, অর্থাৎ,

V = V 1 x V 2

= 250

ইনপুট সিগন্যাল ভোল্টেজ, Vi = 10 mV=0.01 V

দ্বিতীয় পর্যায়ের আউটপুট = Vo

Vo=2.5 V
