Using logic gates, design a circuit that has a capability to perform 4 bit binary addition or subtraction based on the choice of the user. The circuit should accept decimal numbers from the users and the sum will be displayed in a seven segment. Test the designed circuit in a simulation and submit screenshots of sample inputs and outputs. Include in your submission your KMAP Solutions, truth tables and sample manual calculations

The logic circuit below is supposed to be designed to produce the truth table also shown below. However, there is a component missing. Which type of component is missing? х У х 1- 1.

By using MATLAB software with detail solution solve the circuit shown in the Figure attached that consists of a resistor and a capacitor and is thus called an RC circuit. If we apply a sinusoidal voltage , called the input voltage, to the circuit as shown, then eventually the output voltage  , will be sinusoidal also, with the same frequency but with a different amplitude and shifted in time relative to the input voltage. Specifically, if oi Ai sinwt, then oo =Ao sin(wt+o) ,   The frequency response plot is a plot of Ao/Ai versus frequency. It is usually plotted on logarithmic axes.   Upper-level engineering courses explain that for the RC circuit shown, this ratio depends on and RC as follows:   where . For RC=0.1 s, obtain the log-log plot of versus  and use it to  nd the range of frequencies for which the output amplitude Ao is less than 70 percent of the input amplitude Ai.

Design a Programmable Logic Array (PLA) with 3 inputs and 3 outputs. The binary output is two greater than the binary input when the input is 0,1,2,3 and the output is three less than the input when the input is 4,5,6,7. 1.
