Description A smart home is technologically a modern home that uses different types of electronic methods, voice activation methods and sensors to collect specific data Information gained from that data is used to manage assets, resources and services efficiently. By using assembly/Arduino language, keeping in mind finite state concepts, you are required to simulate the functionalities of the Temperature warning system to control room temperature. Using the Arduino simulator integrate with NTC Thermistor that will turn on different LEDs. Green when temp 45C Triggering conditions/events could be passed to microprocessor directly (pulses) or programmatically. Marking scheme:
4. Electronic timers are essentially a) Quartz clock b) Stop watch c) Hour glass d) Egg-timers Answer: a Clarification: Electronic timers are quartz clocks. They are modified with special electronics. They can achieve higher precision when compared to mechanical timers. Electronic timers work on digital electronics which have analog or digital display.
JAVA PROGRAM ASAP ************* THE PROGRAM MUST WORK IN HYPERGRADE AND PASS ALL THE TEST CASES.**************** Chapter 16. PC #5. Palindrome Detector (page 1073) A palindrome is any word, phrase, or sentence that reads the same forward and backward. Here are some well-known palindromes: Able was I, ere I saw Elba A man, a plan, a canal, Panama Desserts, I stressed Kayak Write a boolean method that uses recursion to determine whether a String argument is a palindrome. The method should return true if the argument reads the same forward and backward. Demonstrate the method in a program. The program should ask the user to enter a string, which is checked for palindrome property. The program displays whether the given input is a palindrome or not, then prompts the user to enter another string. If the user enters QUIT (case insensitive, then exit the program). Test Case 1 Please enter a string to test for palindrome or type QUIT to exit:\nDesserts, I…

Problem Title: Design and implement a digital processing-based speech quality enhancement system to improve the signal to noise ratio (SNR) of recorded speech signal. Problem Description: Design and implement a digital processing-based speech quality enhancement system for voice signal recorded by you. The details of the design constraints are as follows: 1. Required to record Voice in a noisy environment and perform statistical analysis of the recorded audio signal to find: o Mean o Standard Deviation o Variance o No of Zero Crossings o SNR o Frequency spectrum 2. Based on analysis, design and implement a digital signal processing system for the enhancement of speech signal.
