00:01 So let us start with the concept which we are going to use here for this question.
00:08 Since we know to solve the transistor and its parameter we use the approximate model of that transistor.
00:19 So for the given bjt amplifier shown we are given that beta is equal to 95 and cut -in voltage vt is equal to 26 millivolt.
00:32 For the a part we just need to draw the small signal equivalent circuit by using approximate model while given vcc is equal to 10 volt and then further.
00:50 So let it started with solution.
00:54 So first of all we will draw the small signal model here.
00:58 So as we can see there is an attachment of source that will be right over here then 20 ohm of resistors connected in series with that.
01:10 Now the two resistors will comes in parallel for the small signal model...
