Lecture 21 Introduction to Digital Electronics - Memory, Sequential Circuits


Topics :- Cells, Types of memories - SRAM, DRAM and flash, SRAM from inverter and RS flip flop.

Technology

In lecture 20 Introduction to Digital Electronics - Transistors, CMOS Gates the topics taught were CMOS transistors - NMOS and PMOS, construction of inverter and NOR gates with the use of CMOS transistors. What is interesting in this lecture is how simple the NMOS and PMOS transistors were drawn. This is a good lecture.

Technology

In lecture 19 Introduction to Digital Electronics - Boolean Algebra
the topics taught were amplitude quantisation, sampling clock, inverter, AND gate, OR gate and adder circuit.

Technology

In lecture 18 Introduction to Digital Electronics - Review the topic about bandpass filter was continued here.

Technology

In lecture 17 Introduction to Digital Electronics - Filters the topics taught were frequency domain, low pass filter and bandpass filter. High pass filter was taught in the last lecture. The bandpass filter which is a combination of the high pass and low pass filter can be used in RF (radio frequency) communications.
