Combinational Logic If the inputs to a full adder are A=1, B=0, CIN=1 what will be the logic states on the outputs S and COUT? S=0 COUT=0 S=0 COUT=1 S=1 COUT=0 S=1 COUT=1 None What is the main purpose of the Ripple Blanking facility on some decoder ICs? It allows decoder ICs to be connected in cascade. It prevents the display of digits greater than 9 on decimal displays It blanks leading and trailing zeros. It increases the speed of decoding. None How many outputs would two 8-line-to-3-line encoders, expanded to a 16-line-to-4-line encoder, have? 3 4 5 6 None When adding an even parity bit to the code 110010, the result is ________. 1110010 1111001 110010 001101 None What is the range of memory that can be addressed in a memory system, using a 16-bit address bus, 8Kbyte memory chips and a single 3 to 8 line address decoder? 8192 memory locations. 64 x 8Kbyte memory ICs. 65536 memory locations 2Mb memory locations None In a two-gate half adder circuit, which of the listed gates would produce a Carry output? OR NOR XOR AND None How many 1-of-16 decoders are required for decoding a 7-bit binary number? 6 8 10 11 None Which of the following expressions is in the product-of-sums form? . (A + B)(C + D) (AB)(CD) AB(CD) AB + CD None A digital system is required to amplify a binary-encoded audio signal. The user should be able to control the gain of the amplifier from a minimum to a maximum in 100 increments. The minimum number of bits required to encode, in straight binary is 2 5 7 10 None Which of the following combinations of logic gates can decode binary 1101? One 4-input AND gate One 4-input AND gate, one OR gate One 4-input NAND gate, one inverter One 4-input AND gate, one inverter None Time's up
