Digital Circuits Lecture-12,13&14: BOOLEAN ALGEBRA

Digital Circuits Lecture-12,13&14: BOOLEAN ALGEBRA
                                     In this lecture, i discussed the concept of Boolean algebra and its applications in digital circuits. and i also discussed what are the theorems, properties and axioms used in the Boolean algebra.
                             The very important principle called duality is discussed and its application.and i solved few problems on minimization of Boolean functions and how to complement of given Boolean functions.

Signals and Systems Lec-57&58: Digital Filters

Signals and Systems Lec-57&58: Digital Filters:
                             In these Lectures, concept of digital filters is introduced. I discussed what is a digital filter and its applications in digital signal processing and how to characterize and realization of filters.
                            And also discussed various types of filter i.e IIR digital filters and FIR digital filters and their classifications like IIR-Lopass filter(LPF), Highpass filter(HPF), Bandpass filter(BPF), Bandstop filter(BSP) and FIR-LPF,HPF,BPF.

Signals and Systems Lec-55: Block Diagram Representation for Discrete-time LTI Systems

Signals and Systems Lec-55: Block Diagram Representation for  Discrete-time  LTI Systems
                                In this Lecture, concept of block diagram representation for discrete-time  LTI systems  is discussed using z-transform. i.e different types of realizations like direct form 1 and 2, cascade form and parallel form are explained through the example problems. And i also solved previous GATE questions.
