How would we make a schematic design for a vending machine that accept nickels, dimes, and quarters, and sells drinks at 30 cents each? (disregard changes and there is only 1 type of drink) 2 Hexdecimal values must show the current money input (binary to hexadecimal converter is given), and when the value hits 30 or more, reset the current amount to zero, and LED should be lit to represent a successful. For the flip flop, D-flip flop should be used for simplicity.

For all the requested figures below, use a discrete time range
of n = [0,50] on the x-axis. Remember your script should be
self-sufficient and run without any errors to receive any
points.
You are given a discrete time system (1) below (same system as
Homework 5(a)):
(E - 0.2)(E - 0.4)(E - 0.6) y[n] = (2 - 3E)
x[n]
(1)
Question 1. Compute the impulse response h[n] of system (1) above,
using the recursive solution method. You will not receive any
points for using another method. Given the system input x[n]
defined by equation (2) below, compute the output yr[n] to the
system (1), using h[n] you have just computed and x[n], by discrete
convolution. You will not receive any points for computing yr[n]
using another method.
x[n] = cos( pi x n/32)
u[n]
(2)
Display computed yr[n] together with y[n] you have computed in
Homework 5(a) on the same figure. Display yr[n] in red circles
(‘ro’), and y[n] in blue stars (‘b+’). You are NOT asked to display
h[n], do NOT display h[n]. Do not forget to properly label and
annotate your figure and follow the time range requirement set on
the top of this page. You will not receive full points
otherwise.
Note: Use a stem plot, with the help of the built in Matlab
function “stem()” in order to properly represent a discrete signal
on a figure.

A DSB signal is squared to generate a carrier component
that may then be used for demodulation. (A technique
for doing this, namely the phase-locked loop, will
be studied in the next chapter.) Derive an expression that
illustrates the impact of interference on this technique.

The goal in this experiment is to implement a 0-12 counter with a test bench that displays the output of each of the flip-flops in the counter. A behavioral code should be written for this experiment.
Set the time format to 1 nanosecond with a precision of 100 picosecond.

Signal transduction refers to any process of changing one signal to signal of another type. An example would be a series of pulsing lights into the sound for the word: "Help". Discuss how this transduction could be done by a device.

A 100 hp, 220 V, 1200 rpm DC shunt motor with an armature
resistance of 0.05 ? and a field resistance of 50 ?. The motor has
compensating windings, so armature reactance can be ignored.
Mechanical and core losses may be ignored also. The motor is
driving a drilling machine, TL ? (1/n). The motor is driving a load
with a line current of 120 A and an initial speed of 1200 rpm.
Assume Linear Magnetization curve
i. What is the motor speed if the field resistance is increased to
55?? While supplying a constant-torque load
ii. Calculate the motor speed as a function of the field
resistance, assuming a constant-Load Torque. Plot the motor speed
as a function of the field resistance.
