Compare AM (Amplitude Modulation) with FM (Frequency Modulation) in the context of modulation techniques, frequency range, bandwidth requirements, complexity, noise, and hardware.

ASAP In this lab, you will make a digital thermometer using the SEN-11931 breakout board as well as the 4-bank seven-segment LED display. Design the hardware connection of the SEN-11931, reuse the 4-bank 7-segment LED connection from Lab 4 for the mbed to read the temperature from the SEN-11931 and display the temperature in Fahrenheit degrees on the LED display in the format of xxx.x. Build your circuit and include all the required information about your hardware design in your lab report. You will also need to make the decision on whether pull-up resistors are needed. Based on the hardware you designed, write a code that takes temperature measurement every 5 seconds and display the temperature in Fahrenheit degrees in the format of xxx.x (for example: 098.6 or 104.8) on the 4-bank seven-segment LED display.

In a computer system with multiple types of memory (such as RAM and ROM), how does the computer identify where memory is stored?

Develop a series RLC circuit that increases the capacitor voltage to the source voltage as fast as possible with no more than a 20% overshoot. The source voltage is 99V, the capacitance is 9F the and the inductance is 23 H. You can adjust the resistance since that the inductance are the two easiest parameters to adjust. I suggest you find ω0 for your circuit and the value of R that results in a critically damped circuit. Plot this vs. time using Δt ≈ 0.1/ω0. Plot the under damped response on the same set of axes. Hint – the resistance will be lower than for the critically damped circuit. Adjust the resistance to so that the capacitor voltage reaches the source voltage as soon as possible without overshooting by more than 20%.

I need to obtain an approximate implementation of a Butterworth low pass first order filter using P-spice. It suppose to have a cutoff frequency of 1000Hz and the attenuation cutoff frequencies fixed at 3db.

1. Determine the ROC for stability for transfer function H(s) = 1 / (s-2) ( s-1)

2. Determine the ROC for stability for transfer function H(z) = (z-1) / (z+0.1) (z-0.2)

Effective Engineering in today’s world requires intelligent use of all potential engineering tools. One of the most significant tools is modeling, whether it is hand models or complex computer models. Hand models are simplified models which contain the prominent elements of system or circuit behavior. Computer models permit the inclusion of second and third order details to more accurately reflect real world behavior. When using any model, however, it is critical that the model be valid, accurate, applicable, and useful. For this assignment, you will analyze the effective of a system model. You may select an example from work, from a company or experience you had in the past, or invent an opportunity that should exist.

1)    Explain the theory: Select a company, and/or company product which rely on modeling to develop, debug, or improve the product.

a) What is the primary product(s) of the company? What product, or process, etc. was modeled?

b) Briefly describe the application, and the modeling tool.

2)    Discuss the effectiveness of the modeling tool by considering the strengths, weaknesses, opportunities or threats of using the modeling tool

a) What benefits are there? Give 3 specific benefits to the company of the modeling.

b) What risks are there? Give three specific examples of information or reactions not adequately or accurately reflected in the model. What risk do these generate for the company?

Design a 8086 microprocessor base system that manage 1Mbyte of memory and can handle serial and parallel communication, a keyboard, a screen, a printer and a USB connection that handle high capacity secondary memory. Show all the connections needed and use all the necessary family chips needed to handle the I/O Systems. Show the memory map needed and the necessary I/O drivers. Use an interrupt manage chip to handle the I/O devices to be connected.

What is a difference between syncronous and asynconous machine?

Please give specific examples and problem related.

Below is the sample, please provide the equations, the picture of the given explanations, and the problem related to these.

(i) Synchronous motor is a machine whose rotor speed and the speed of stator magnetic field is equal.

Asynchronous motor is a machine whose rotor rotates at the speed less than the synchronous speed.

(ii) Synchronous motor does not have slip. The value of slip is zero.

Asynchronous motor has slip. Therefore, the value of slip is not equal to zero.

(iii) Synchronous motor is costly as compared to Asynchronous motor.

(iv) Efficiency of Synchronous motor is greater than Asynchronous motor.

(v) Synchronous motor is not self starting whereas Asynchronous motor is self starting.

(vi) Synchronous motor operates smoothly and relatively good at low speed that is below 300 rpm, whereas Asynchronous motor operates at high speed that is above 600 rpm.

(vii) Current is given to the rotor of synchronous motor whereas the rotor of Asynchronous motor does not require any current.

(viii) Change in applied voltage does not affect the torque of synchronous motor, whereas it affect the torque of Asynchronous motor.

One example of a synchronous motor is the "stepping motor" which widely used in applications that involve position control. One example of asynchronous motor is "Centrifugal Pump" which widely used in buildings for pumping the general water supply, as a booster and for domestic water supplies.
