समाधान:

पहले एम्पलीफायर का लाभ, V1 = 10

दूसरे एम्पलीफायर का लाभ, V2 = 25   

दो चरण वाले कैस्केड एम्पलीफायर का कुल वोल्टेज लाभ दोनों चरणों के वोल्टेज लाभ के गुणनफल द्वारा दिया जाता है, अर्थात,

V = V1 × V2

   = 250

इनपुट सिग्नल वोल्टेज, Vi = 10 mV=0.01 V

माना दूसरे चरण का आउटपुट = Vo

 Vo=2.5 V
