(b) An aperiodic signal defined below is the input signal to a system is sampled at 4000Hz rate: x(t) = cos(2π1500t) + 2cos(2π1550t) 0≤t≤T The signal needs to go through DFT/FFT block function before it can pass to other system. (i) Determine the minimum sample size N (ii) Find sampled signal x[n]. (iii) Based on the minimum sample size N, calculate the frequency spectrum DFT for the given signal x(t).

What are the output values of a 3-bit magnitude comparator with active HIGH output functions AEQB, AGTB, and ALTB for the following input values: 1. a. A = 010, B = 101 b. A 000, B = 111 c. A=010, B = 010 d. A = 110, B = 101 (Ctrl)

A Data Acquisition Device (DAQ) receives a signal from a thermocouple used for temperature measurement. The thermocouple signal varies from 0 to 45 mV for a temperature range of 20ºC to 1800ºC. The DAQ has the following configuration options: Resolution: 12 Bit / 16 Bit Range: 0 to 10 V / -10 V to 10 V Amplification: 1, 10, 20, 100 What configuration should be selected to detect a change of 0.1ºC? Explain why

Question 1 In this problem, you are required to design a 30-channel FDM multiplex for the transmission of voice signals. There are two bands available with the following frequency ranges: Band 1: 50 kHz - 80 kHz Band 2: 200 kHz - 230 kHz It is also required to have a 2 kHz guard band (no guard band is required is the beginning, i.e., before the first user) between each adjacent signal to avoid signal interference (for band 1). For band 2, 3 kHz guard band is required between each adjacent signal to avoid signal interference (no guard band is required is the beginning, i.e., before the first user). Draw a clear block diagram of your 30-channel. The diagram must show the number of stages of the multiplexer, the starting and the terminal frequency of each stage, the frequency of each guard band in each band, and the frequency of each user in each band (refer to last slide of chapter 4c pdf file). You should also describe the details of your design to get full credit.
