esign a 4-bit combinational circuit that counts DOWN and UP. Counts 1 - 7 only. The first and the last input is 1111. Include the truth table, simplified equation, and decoder implementation.

6) The Binary number 110111 is equivalent to decimal number (A) 25 (B) 55 (C) 26 (D) 34 7) With 4 bit, what the range of decimal values if the number is 2's complement signed number. (A) -32 to +31 (B) -2 to +1 (C) -8 to +7 (D) None of these

An eight bit number, 01011101, is:    1)added to 4   2) subtracted from -10   3) ANDED with 15 a) What is the outcome of these operations in binary? b) What is this number in decimal? c) What is the original number in decimal?

Create a circuit to generate odd parity bit for a 3-bit code. a.  Construct the truth table. b.  Use K-map to simplify the circuit. c.  Draw the circuit with minimum number of gates. (I did the question myself, but I'm confused as to why the K-map does not provide the simplified circuit to build the minimum number of gates)
