Extracted text: True or false : A half-adder has no carry-in bit. 1 2 Adders with greater bit capacities can be constructed by connecting 2-bit adders in parallel Full-adders do not provide for a carry input or a carry output 3 4 When paralleling 2-bit full-adders, the carry-out next-higher stage. Full-adders can be used as a BCD-to-binary converters each stage is connected to the carry-in of the A BCD-to-decimal decoder can be classified as a 4-line to 10-line decoder A BCD-to-7-segment decoder can be classified as a 10-line to 7-line decoder 8. The function of a decoder is to break a decimal or other character code down into a binary code Converting a decimal number to its binary equivalent is an example of encoding 10 A multiplexer has multiple inputs and a single output A multiplexer has multiple inputs and a single output 12 A demux basically reverses the function of a mux 11 13 AD flip-flop is constructed by connecting an inverter between the Set and Clock terminals of a S-R flip-flop. 14 The J-K flip-flop toggles when both inputs are high during the transition of the clock signal 15 A pulse-triggered flip-flop is identified by a bubble on its Qoutput terminal 16 A serial-in, serial-out shift register is used to transfer data one bit at a time from one line of a parallel bus to another. 17 The serial-in, parallel-out shift register is used to transfer data one bit at a time from one parallel data bus to another. 18 A parallel-in, serial-out shift register accepts all data bits simultaneously and transfers them out one bit at a time. 19 term synchronous refers to events that do not occur at the same time. 20 The term synchronous as applied to counter operations means that the counter is clocked so that each flip-flop in the counter is triggered at the same time. 21 Another term used to describe up/down counters is bidirectional. 22 Once an up/down counter begins its count sequence, it cannot be reversed 23 Most sequential circuits contain a combinational logic section and a memory section 24 Basic counters can be cascaded to increase the number of count states the counter can produce 25 The NAND gate is an example of combinational logic. 26 The commonly accepted abbreviation for an exclusive-OR gate is XOR 27 X= ABC + BCD is in the form of a sum-of-products expression 28 The Karnaugh maps provide graphic approaches to simplifying Boolean expressions 29 Sum-of-Product (SOP) form is a standard form of Boolean expression 30 Product-of-Sum (POS) form is a standard form of Boolean expression 31 When mapping an SOP expression using a Karnaugh map a 0 is placed in each cell corresponding to the value of the product term.
