Part 1) What are the suitable sampling frequencies for correctly capturing surface EMG and explain why? Part 2) Discuss what are the possible noises that may affect the EMG signal during the detection. Part 3) To demonstrate the bipolar configuration in capturing EMG signals, please draw a schematic diagram when using surface electrodes for EMG detection and illustrate how the common mode noise is reduced.

EMG signal processing For this question, you are going to work on EMG_final.mat file. There are 84 channels simultaneous recordings were saved in this file, not all of them emg data. 1.1 After you load the data, investigate it, answer following questions (10 points). Answer following questions 1. How many emg channels are present. (1 points) 2. What are the names of muscles investigated. (1 points) 3. What is the sampling rate for emg channels. (2 points) 4. How the emg recordings are saved? In columns or rows. (2 points) 5. Is the time vector provided? (2 points) 6. How the time recordings are saved? In columns or rows. (2 points)

Discuss in detail, how the Piezoelectric Effect is used in the generation and detection of Ultrasound waves. Explain the functions of the various layers of a typical ultrasound transducer. Why are thicknesses of 1/2 and 2/4 used for the piezoelectric layer and the matching layer? For a piezoelectric material with an ultrasound velocity of 6000 m/s, what thickness should a disk-shaped crystal have to provide an ultrasound beam with a frequency of 2.5 MHz?

What is sampling? How frequently should it be? What is the Nyquist Criterion for sampling signals? What happens if we sample at a lower rate or a higher rate than the Nyquist rate? What will be the right sampling rate for an Audio Signal? Why do we choose the sampling rate close to the Nyquist rate and not a very high rate? What is quantization? What is the difference between linear and nonlinear quantization? How is an audio signal quantized? How do we reconstruct the original signal back from the digitized signal? What is a low-pass filter? What is Analog to Digital Conversion (ADC)? What are commercially available ADCs? What should be a good criterion for the selection of an ADC?
