Introduction to Digital Logic Design

A brief introduction to digital logic design course. The hierarchy of the processor in the mobile phone, laptop etc. In the next level we have register transfer. Inside of the register we have gate level circuit and in each Gate we have the semiconductor devices, the transistors. let me give a simple analogy, if you assume processor like a living room, inside that room we have cupboards which are analogous to registers, and in the cupboards we have pencil box with pencils, erasers etc. Here a Gate is like a pencil box and the pencils are like the semiconductor transistors. Define Analog system Define Digital system understand the Difference between digital and analog systems The Advantages of digital systems over analog systems States or logic levels in digital systems Binary number system Bit Sequence of bits, Code Logic level Digital waveform Ideal pulse Non-ideal pulse Rise time Fall time Pulse width Duty cycle Reasons for Overshoot and ringing: Stray inductance or capacitance in the circuit Reasons for Droop: Stray capacitance or resistance in the circuit with low time constant The characteristics of Waveforms Public address system an example of analog system How is analog to digital conversion done, an idea.
