Question

Transcribed Image Text:This process is known as cascading. Notice that, in this case, the output carry is
designated Cg because it is generated from the eighth bit position. The low-order adder is
the one that adds the lower or less significant four bits in the numbers, and the high-order
adder is the one that adds the higher or more significant four bits in the 8-bit numbers.
Similarly, four 4-bit adders can be cascaded to handle two 16-bit numbers.

It generates the binary code corresponding to the input value. The following figure shows a block diagram of 8-to-3 encoder. There are eight inputs, i.e. D7 through D0, and three outputs (binary code), i.e. B2, B1 and B0. Answer the following questions. (Note: You should show all the steps) 1. If the input D7 is high (or “1”) and the other inputs are low (or “0”), what binary code does the encoder generate? 2. Draw the complete truth table of 8-to-3 encoder.arrow_forwardcan someone help me please and solve this questions with steps pleasearrow_forward

- Please do this, urgently needed.arrow_forward1. Gray code to Binary converter: Gray code is one of the codes used in digital systems. It has the advantage over binary numbers that only one bit in the code word changes when going from one number to the next. (See Table 1). Design a combinational circuit with 4 inputs and 4 outputs that converts a four- bit gray code number into an equivalent four-bit Binary number. Use Karnaugh map technique for simplification. Use LogicWorks for pre-lab demonstrations. Select the library "7400dev.clf* in the Parts Palette and then select the XOR chip 74-86. This would give you a set of 4 XOR's as shown in Fig. 1, just like the hardware chip 74-86. You could use as many as needed from these XOR gates in your design. Get back to ALL LIBRARIES and select switches for the inputs and Binary Probes as indicators of the outputs. Verify your design in the pre-Lab. During the Lab construct the circuit and verify its operations.arrow_forwardComplete the Hamming code below for the given 4-bit hex values. Insert the ODD parity bits into positions 1, 2, and 4.

In the circuit implementation of an 8-bit adder, explain why the carry bit connection of the least- significant bit is connected to ground. Explain in words what values for A, B, C, D, E will cause a 1 to appear at point X. The circuit below uses a 5-input AND gate. Draw the equivalent circuit using only 2-input gates.arrow_forwardFor a 4-bit parallel adder, if the carry-in is connected to a logical HIGH, the result is O a. The carry-out is ignored b. The same as if the carry-in is tied LOW since / the least significant carry-in is ignored O C. A one will be added to the final result o d. That carry-out will always be HIGHarrow_forward
