A four-bit control code (C0, C1, C2, C3) is used in a digital system. Only the eight codes shown in the table are used. Any unused code is considered to be invalid. Design a combinational circuit that confirms that the current control code is valid. In other words, obtain a logic diagram with four inputs (C3, C2, C1, C0) and one output (V). V is equal to 1 when the inputs contain one of the valid control codes below and 0 for all other conditions.

task 1: In digital electronics and modern computer hardware, a flip-flop is sequential digital circuit used as a basic memory element. It has two stable states and can be used to store state information. One of its states represents '1' while the other represents '0'. The most common types of flip-flops are SR-flip-flop, JK-flip-flop, and D flip-flop. When used in a finite-state machine, the output and next state depend not only on its current input, but also on its current...

BIT MAXIMUM VALUE SELECTOR Consider a simple device that takes two 2-bit binary inputs representing two values ranging from zero to three. The 2-bit value A is represented by two input variables Al and A0. Values of Al and A0 will be used to encode numeric values (in binary) as described below. 2-bit values for the second 2-bit input B and the 2-bit output C are encoded similarly. The 2-bit output C of the de- vice will be the greater...

The task is to design a two-bit controlled counter which has two
counting bits (Q2, Q1), has one control input C1, and also two
extra outputs, one indicating overflow, the other underflow.
When C1=0 the counter counts up by 2s; i.e. 0 becomes 2, 1
becomes 3. In this mode the values 2 and 3 go to the overflow
state. When the control input C1=1, the counter counts down by 2s,
i.e. 3 becomes 1, and 2 becomes 0, and...

2. The decimal digits 0 to 9 are represented by four logic signals using the 7321 weighted BCD code. Only the code 0011 is used to represent the digit 3. In addition the code 1100 is used to represent the character E. Codes that do not represent either a decimal digit (including 0100), or the character E never occur. The logic signals are inputs to a decoder circuit whose outputs provide drive signals for a seven segment display system shown...

number 4 and 5 please!
PROBLEM STATEMENT A logic circuit is needed to add multi-bit binary numbers. A 2-level circuit that would add two four-bit numbers would have 9 inputs and five outputs. Although a 2-level SOP or POS circuit theoretically would be very fast, it has numerous drawbacks that make it impractical. The design would be very complex in terms of the number of logic gates. The number of inputs for each gate would challenge target technologies. Testing would...

Binary Coded Decimal (BCD) weighted 7-4-2-1 code. V is a validity bit that =1 when the input code is valid, assume invalid codes can be treated as “don’t care” conditions for W,X,Y and Z. Fill in the truth table for this design A,B,C,D will be the input BCD code and W,X,Y,Z will be the output code. Is this correct? Decimal equivalent Inputs (BCD) (MSB -> LSB) Outputs (7421) (MSB -> LSB) A B C D W X Y Z V...
