A manufacturing plant needs to have a horn sound to signal quitting time. The horn should be activated when either of the following conditions is met: 1. It's after 5 o'clock and all machines are shut down. 2. It's Friday, the production run for the day is complete, and all machines are shutdown. Design a logic circuit that will control the horn. (Hint: Use four logic input variables to represent the various conditions; for example; input A will be HIGH only when the time of day is 5 o'clock or later)

d) Draw the schematics of 4-bit synchronous and asynchronous MOD-8 counters and comment on their pros and cons. e) Calculate the noise margin for a logic gate with the following logic levels: VIL = 1.1 V, VIH = 3.2 V, VOL = 0.6 V, VOH = 4.0 V.

Please may you give the solution to this computer science question! Thank you

What are the values of the inputs a, b, c, d, e, f and g for a Seven-Segment LED that displays the number 2? Assume active high logic. a) 1101101 b) 1010101 c) 1101110 d) None of the above e) All of the above

Create a complete analysis table for the circuit by finding the logic leveis present at each gate output for each of the 16 possible input combinations.

Q1. (a) Design a stick (layout) diagram for the following static CMOS logic gate, where A, B, C, D are the logic gate inputs and O/P is the output: VDD D-d[Q8 A-Q5 B-Q6 c-d[Q7 O/P CQ3 DQ4 B-Q2 A-Q1 Vss Figure 1 Use dual-well, CMOS technology. Include wells, well-taps, contact cuts, routing of power and GND in your diagram. Use colour coding and/or clear and readable detailed annotations to represent the wires in the different layers.

Hi. Please may you give the solution to this question in a step by step form to help my understanding. Both parts need to be completed in order to answer

None

Q1. (a) Design a stick (layout) diagram for the following static CMOS logic gate, where A, B, C, D are the logic gate inputs and O/P is the output: VDD D-d[Q8 A-Q5 B-Q6 C-d [Q7 O/P CQ3 DQ4 B-Q2 AQ1 Vss Figure 1 Use dual-well, CMOS technology. Include wells, well-taps, contact cuts, routing of power and GND in your diagram. Use colour coding and/or clear and readable detailed annotations to represent the wires in the different layers. (b) The logic gate from (a) needs to drive a capacitive load of 150 fF with a rise-time and fall-time of 1.2 ns. If the length of all transistors is 0.5 μm, calculate the required widths for all P-type and all N-type MOSFETs in the logic gate to achieve the required edge-speeds. Clearly show the calculation steps of your solution. Assume VDD = 5 V, K'n = 50 μA/V², K'p = 20 μA/V²

parity generator design, construct and test a circuit that generates an even parity bit ffrom four messages bits . use XOR gates. adding one more XOR gate, expand the circuit so that it generates an odd parity bit also.
