Logic Families : Circuit concepts and comparison of logic families : TTL, CMOS NMOS and ECL; characteristic parameters : logic levels/fan-in and fan-out, noise margin, propagation delay and power consumption.Minimization of Boolean Functions using (i) Karnaugh Map having don't care entries and (ii) tabular method.Arithmetic Logic Circuits : Representation of negative numbers, 9's and 1's complements 10's and 2's complements, arithmetic using 2's complements. Adders and Subractors, magnitude comparator.Combinational Logic Circuits : Multiplexers / Demultiplexers, encoders/decoders, PAL and PLA.Sequential Logic Circuits : Latches and Flip-Flops : SR, D, T, JK and Master-slave Jk.Shift Registers : Basic principle, serial and parallel data transfer, shift left/right register, universal shift register.Counters : Mode N counters, ripple counters, synchronous counters, ring and Johnson counters.Memories : Read Only Memories ; Random Access Memories; Static and dynamic; sequential memory : Memory Organisation.Linear Wave Shaping : RC low pass and high pass circuits and response to sine and square wave inputs, RC circuit as differentiator, integrator and compensated attenuator.Converters : Sample and hold circuit, A/D and D/A converters.The time constant of a series RC circuit is known as RC -time constant and it is a product of the resistance and the capacitance. The symbol for ... Time constant is the time required for the charging current of the capacitor to drop to 0.368 of its initial maximum value. The discharge ... It consists of three input signals, one output signal and three units : charging unit, comparator and output unit. The charginganbsp;...
