a) Design a single-digit decade counter that counts from 0 to 9 and repeats. The single-digit decade counter should be built by a cascaded synchronous binary counter (74LS163) and other basic logic gates. Simulate thecomplete counter circuit by OrCAD and PSPICE. Capture the circuit schematic and the simulated waveform.(Define the simulation timings for at least one full counting cycle from 0 to 9 and back to 0.)(Hint: Use the DigClock input from the SOURCE as shown below and setup the CLK ONTIME and OFFTIME accordingly for the clock source.)
answere fast please question from DIGITAL LOGIC DESIGN TOPIC : Designing Combinational Logic You are designing a water level circuit using 74ALS151 (8 to 1 Multiplexer IC)* When input is 0000 that means tank is empty.* When input is 1111 that means tank is full.* When input is below 5, that means water level is low.* So, make a circuit using 74ALS151 Multiplexer IC that shows a "low water" indicator light(by setting an output L to 1) when the water level drops below level 5.
