Here I am sharing the previous year Question Paper of JNTU for B.Tech Electrical and Electronics Engineering-2nd Year Pulse and Digital Circuits Exam

1.
What is the ratio of the rise time of the three sections in cascade to the rise
time of Single section of low pass RC circuit. [8+8]

2.
(a) Draw the circuit diagram of slicer circuit using Zener diodes and explain its
operation with the help of its transfer characteristic.
(b) Draw the circuit diagram of emitter coupled clipper. Draw its transfer charac-
teristics indicating all intercepts, slopes and voltage levels derive the necessary
equations. [8+8]

3.
(a) Explain the terms pertaining to transistor switching characteristics.
i. Rise time.
ii. Delay time.
iii. Turn-on time.
iv. Storage time.
v. Fall time.
vi. Turn-off time.

(b) Give the expression for risetime and falltime in terms of transistor parameters
and operating currents. [6+10]

4. In the nonsaturated binary shown in figure 4, the avalanche diodes D1 and D2 are
nominally identical, as are diodes D3 and D4. The breakdown voltage V?Z of D3
and D4 is larger than the breakdown voltage VZ of D1 and D2. Verify that the
transistors do not enter the saturation region. Assume that D3 and D4 are always
in the breakdown region and that either D1 or D2 but not both, is in the breakdown
region. Then verify these assumptions.

The paper deals with digital circuits and their applications; this is a vital thing in the future prospect as the entire communication things run on the digital circuits.

Type of paper:
It contains 8 questions. The questions are of equal marks. Each question is divided into 2 sub-questions for the ease of candidates. From 8 questions, candidates are required to solve 5 questions. Questions of this paper are both subjective & numerical type. There are some questions in the paper which are of circuit diagram based type.

Marks and time:
The paper is of 80 marks and time allotted is 3 hours only. Each question is of equal marks. Mean 1 question of approximately 20 marks.

I m also providing you some papers:
