4. Three amplifiers with gains of 15, 22, and 7 are cascaded; the input voltage is 120 µV. What are the overall gain and the output voltages of each stage?.
In case of amplifiers which are cascaded the overall gain becomes the product of gains of all the amplifiers ex: overall gain of amplifiers A,B,C is overall gain= A*B*C In our case it is Av=15*22*7=2310 When the input voltage
