Welcome to this detailed lecture on CFG to PDA Conversion in Theory of Computation.
In this video, we explain how to convert a Context-Free Grammar (CFG) into an equivalent Pushdown Automaton (PDA) and explore the deep relationship between CFGs and PDAs.

📘 Topics Covered:
✅ What is the equivalence of CFG and PDA?
✅ Why every CFL has a PDA and every PDA has a CFG
✅ Step-by-step conversion of CFG → PDA
✅ Two major cases:
1️⃣ If the Grammar is NOT in GNF (General Form Conversion)
2️⃣ If the Grammar IS in GNF (Direct PDA Construction)
✅ Use of ε-transitions and stack operations
✅ How PDA simulates grammar productions
✅ CFG → PDA Construction Example
✅ Importance of PDA–CFG equivalence in Automata Theory
✅ Explained clearly for GATE, TOC, and University Exams

This video is ideal for anyone learning Formal Languages, Automata Theory, Compiler Design, and TOC.
Grab your notebook and follow along step-by-step to master CFG to PDA Conversion.
