JNTUK R23 B.Tech ECE III Year I Semester (3-1) Syllabus & Subject-wise Topics

The table also lists optional Minor-degree and Honors-degree course rows (a student may pick from a separate Minors/Honors subject pool such as Advanced Communications, EMI/EMC, RTOS, or Digital Electronics). These are add-on degree tracks rather than core curriculum, so they are not expanded unit-by-unit here.

• Unit 2: Basic computer organization, instruction cycles, and micro-programmed control
• Unit 3: CPU organization, addressing modes, and computer arithmetic algorithms

• Unit 5: Memory hierarchy — cache, virtual memory, and memory management hardware

Open Elective-I

the table allows either a subject from the university-wide open-elective pool or a fixed alternative, Entrepreneurship Development & Venture Creation; no unit-wise syllabus for the Entrepreneurship option appears anywhere in this document, so it can’t be summarized honestly here.

Open electives offered by the ECE department (Pool 1)

the ECE syllabus document also carries full syllabi for four subjects it offers as open electives to other branches (Pool 1, mapped to the university’s Open Elective-I slot):

• Electronic Devices and Circuits — the same core content as the II Year I Semester Professional Core subject above, condensed for non-ECE branches.
• Signals and Systems — the same core content as the II Year I Semester Engineering Science subject above, condensed for non-ECE branches.

• Probability Theory and Random Variables

  a standalone probability-and-random-process course offered to other branches, mirroring the ECE core Probability Theory and Stochastic Process subject but framed for general engineering use.

• Unit 1: Random variable definitions, distribution/density functions, and standard distributions

• Unit 2: Expectation, moments, and transformations of a single random variable
• Unit 3: Multiple random variables, joint distributions, and the Central Limit Theorem
• Unit 4: Random process classification, stationarity, and correlation functions

• Unit 5: Power spectral density and the response of linear systems to random inputs

• Network Analysis

  covers circuit-theory fundamentals (transients, AC steady state, two-port networks) that other branches need as a foundational electrical circuits course.

• Unit 1: Network elements, Kirchhoff’s laws, mesh/nodal analysis, and phasor representation

• Unit 2: Transient analysis of RL, RC, and RLC circuits under DC/AC excitation
• Unit 3: Steady-state AC circuit analysis and coupled-circuit theory
• Unit 4: Resonance (series/parallel) and network theorems (Thevenin, Norton, superposition, maximum power transfer)
• Unit 5: Two-port network parameters (Z, Y, ABCD, h) and their interconnection

Analog & Digital IC Applications Lab

hardware/simulation practice pairing op-amp circuits with digital IC design flows.

a 2-credit evaluation component tied to the community-service work; the course structure lists only its credit weight, with no separate unit-wise syllabus provided in the document.
