Analog And Digital Electronics

Analog Electronics Special Diodes: LED, Varactor diode, Photo diode, Schottky diode, Tunnel diode Their characteristics and applications. Transistors as a switch. Frequency Response: Amplifier transfer function, Low and high frequency response of common emitter and common source amplifiers. Feedback: General feedback structure Properties of negative feedback Series-series, Series-shunt, Shunt-series and Shunt-shunt feedback amplifiers. Basic principle of sinusoidal oscillator, R-C phase shift and Wein bridge oscillators, Tuned oscillators- Collpits and Hartley Crystal oscillator. Digital Electronics Combinational Logic Circuits: Multiplexers/Demultiplexures, Encoders/Decoders. Sequential Logic Circuits: Latches, Flip-flops- S-R, T, D, J-K. Shift Registers: Basic principle, Serial and parallel data transfer, Shift left/right registers, Universal shift register. Counters: Mod N counters, Ripple counters, Synchronous counters, Ring/Johnson counters. OP-AMP Applications - Astable and monostable multivibrators, Schmitt trigger, IC- 555 Timer, A/D and D/A converters. Voltage Regulators: Series, Shunt and Switching regulators, Op-amp based configurations. Memories: Introduction to ROM, RAM Sequential Memory, Memory organization.
