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.

a- Define Mealy and Moore machines? b- Desian a se detector TAYYADATAYNINUTAonts a: m "7" as Whenever the bit pattern "0100" appears in the input stream, it outputs Z = 1; at all other times, z = 0. Overlapping occurrences of the pattern are also detected.

As the error-detection and correction capability of a code increases, we would expect in general the overhead bits to protect a group of data bits to decrease remain the same increase

Last step in addition to the previous 2 questions: a lengthy derivation using phasors that the first diffraction peak should have an intensity of I1 ≈ 0.045 I0. Using the equation provided below in the pictures and the statement that β = 1.5π, you can find out what θ value to choose. You can also go for the midpoint between the first two destructive interference locations m = 1, 2 in the equation provided in the last question in which I will provide in the second image here. Repeat your three-path amplitude calculations for this value of θ, and observe what the relative intensity is for the first side maximum according to your calculation. Also explain How do the results improved when subdividing the aperture with 5, or 7, or more paths?

What is the rationale for an Error Correction Model?

A sequential circuit has one input X and four outputs Z1 Z2 Z3 Z4. Z1 Z2 Z3 Z4 represents the gray code encoded number equal to the number of pairs of adjacent 1's that have been received as inputs. Use the gray code that is on page 22 of the textbook. For example, if the circuit had received 7 pairs of 1's as inputs, Z1 Z2 Z3 Z4 = 1011. In addition, the circuit resets when the circuit receives 5 pairs of 1's. Find a Moore state graph and table for the circuit.

Explore bitwise operators and their applications in low-level programming. Provide examples of bitwise AND, OR, XOR, and shifting operations.

The output of a combinational circuit which implements a majority function F(x,y,z) is equal to 1 if more input variables are equal to 1 rather than 0. The output is O otherwise, e.g. F(1,1,0)=1, F(0,0,1)=0. Which of the following expressions represent the simplified expression for function F? F = xy + xz + yz OF= xz + xy F = x + zy + z OF = x e y e z
