Design a synchronous 3-bit binary counter that generates the repeated sequence of 0, 3, 4, 7, 0, 3, 4, 7, 0… The outputs of the flip-flops are to be the binary output signals of your counter. Your solution needs to include the input equations for the flip-flops, and a circuit diagram for each version. a) Design the counter using D flip-flops b) Design the counter using T flip-flops c) Design the counter using JK flip-flops

Design and program an Arduino-based circuit that contains the
following items
- 1 Arduino Uno microcontroller.
- 1 IR remote control,
- 1 IR sensor
- 1 LCD 16x2 Display
- Any other components you find necessary.
The circuit will do the following:
- The circuit represents a 2-digit calculator.
- At start of operation, the LCD display should display “0” in line
2 of the LCD display.
- Pressing the On/Off button on the IR remote represents the
“Clear” button of the calculator, the VOL+ represents the “+”
button, the VOL- represents the “-” button, the |<<
represents the “X” button, the >>| represents the “/” button,
the EQ represents the “=” button, and the digits represent the
digits on the calculator.
- The system expects always the following sequence of keys:
[1] Clear,
[2] a digit (representing the 10s of first number),
[3] a digit (representing the ones of first number),
[4] an operation (+, -, X, /),
[5] a digit (representing the 10s of the second number),
[6] a digit (representing the ones of the second number),
[7] Equal
- After a correct sequence of presses is input (total of 7
presses), the display should display something like the following
on the two lines of the LCD:
“17+29= ”
“46 ”
- If a wrong sequence of buttons is pressed, for example: “Clear,
9, X, +, …. “, the system should display “ERROR” in the upper line
of the LCD.
- You may need to use the “#include <string.h>”

At time t = -250/6 μs a sinusoidal voltage is zero and is increasing. The next zero voltage takes place at t = 1250/6 μs and t = 0, it has a value equal to 75 V. This voltage is applied to an inductor, whose inductance is equal 0,0041 H
a) Write the instantaneous voltage equation.
b) The value, in module, of the inductor's reactance.
c) The phasor value of the effective current flowing through the circuit.
d) Draw the phasor diagram of the voltage and current.
e) If the frequency of the voltage signal is reduced in half, determine the modulus of the effective current flowing through the inductor

Typed please. You are working for a company that has developed a new speaker that is supposed to reproduce any and all signals in the frequency range of 20 Hz to 20 kHz with a flat frequency response. You have been selected to test the speaker in order to verify the operation. You are supplied with a microphone that has a flat response, a perfect power amplifier, a white noise generator, and an anechoic chamber. How do you utilize Fourier transforms to test the speaker?
