Digital - ANSWER-Discontinuous Time is only defined at certain times Magnitude can only take on values from a finite set Purpose of binary representation is.... - ANSWER-to put numbers in a form which can be manipulated by digital logic What are the four formalism(representations of logic functions) - ANSWER-1. Truth tables 2. Schematic symbols 3. Boolean (switching) algebra 4. Hardware description language huntingtons postulates - ANSWER-1. Closure x + y are elements of B x * y are elements of B 2.Identity x+0 = x x * 1 = x 3.Distributive x + ( y * z ) = (x + y) * ( x + z ) 4. Complement x + NOT(X) = 1 x * NOT(X) = 0 All Boolean algebraic functions can be generated from either of two sets of two fundamental operators - ANSWER-AND and INVERT OR and INVERT What is propagation delay - ANSWER-Propagation delay is the time between a transition on an input and the corresponding transition on the output. NML = VIL -VOL - ANSWER- NMH = VOH -VIH - ANSWER- Logic hazards can arise due to differences in propagation delay - ANSWER- Logic hazards can (and must be) prevented by proper design - ANSWER- Transistors - ANSWER-Transistors (e.g. MOSFET, BJT) are used to build digital logic gates and circuits. What are the two families of kinds of logic family types? - ANSWER-TTL AND CMOS Logic gates are.... - ANSWER-the building blocks for digital logic circuits Noise margin - ANSWER-The noise margin is the amount of noise that the circuit can withstand and still function properly A negative noise margin implies ..... - ANSWER-A negative noise margin implies that the voltage output by the driver will be misinterpreted by the load(s)
