Digital Signal Processing Questions & Answers

Digital Signal Processing Questions & Answers A AND B - CORRECT ANSWER - A . B A OR B - CORRECT ANSWER - A + B AND gate - CORRECT ANSWER - D shape If A AND B are 1 output = 1 associative law - CORRECT ANSWER - A . (B.C) = (A . B) C carry out - CORRECT ANSWER - an additional output of a counter which allows several digital displays to be connected together to output a number several digits long this output is connected to the clock input of the next counter - each time its signal reaches 1 the next counter will count 1 circuit block for a binary counter - CORRECT ANSWER - ck on the left u/d on the top left MR on the top right Q0 - Qn on the bottom ck - CORRECT ANSWER - clock input - inputs pulses which are counted by the circuit clock rate - CORRECT ANSWER - number of pulses produced per second commutative law - CORRECT ANSWER - A . B = B . A A + B = B + A counting circuits - CORRECT ANSWER - always count in binary but their output can be converted to other forms distributive law - CORRECT ANSWER - A . (B + C) = (A . B) + (A . C) A + (B . C) = (A + B) . (A + C) duty cycle - CORRECT ANSWER - percentage of the time a pulse is in its on state EOR gate - CORRECT ANSWER - OR gate with a curved line at its base if only one of the inputs is one the output = 1 otherwise the output is zero how are astables formed - CORRECT ANSWER - a resistor capacitor network which also contains a not gate which has hysteresis - the not gate will have two switching thresholds resistor in parallel with the not gate
