What is the difference between the PM3 and DFT computational analysis methods? We used them in my lab but they were not explained well.
Lab #2 Discrete-time Fourier Transform (DTFT) OBJECTIVES: • Explore the DTFT, its meanings and concepts. • Get acquainted with Matlab/Octave 1) Start MATLAB and change the “Current Directory” in the top of the window (or type) >> cd '' (example: >> cd 'C:\NIU\lab2') Alternatively, if you don't want to use MATLAB, you can open a web-browser and go to “octave-online.net”. 2) Download and execute LAB2forStudent_A.M with >> lab2forStudent_A and observe that it produces a Discrete-Time (DT) signal xVec. 3) TO...

For Long Term Evolution, LTE, What is resource block in LTE? Explain the difference between reference signal (RS) and synchronization signal (SS) in the LTE and what they are used for? a) b) c) If the design of LTE just met the coherence time of the channel, what was the assumed coherence time? d) The maximum rms channel delay spread considered in the LTE standard is 991 ns. Using equations determine whether the 15kHz wide subcarrier will experience frequency selective...

measurements. please show work to all. Thanks! Remark Do not use computer software. Use a calculator only, and show your calculation process Q1. We have an analog signal Y[V] sin(2π*St). We are collecting this signal with a sampling frequency 20 Hz with analog-to-digital (A/D) converter. Draw the output of A/D converter.

Can someone please help me with all these questions please? I desperately need it asap! Must be done with MATLAB. Thumbs up will be guaranteed! Thank you so much!! A. Discrete Fourier Transform and zero padding For the signals x1[n] and x2[n] answer the following questions: x2 [n] = cos(2m30/100) + 0.5 cos(2nn40/100) 1) Compute and plot the length-N DFT magnitude of signals x1[n] and x2[n] with respect to frequency fr, where f and N is the number of samples....
The representation of a p(t) signal in the frequency spectrum that we want to exemplify is P(f) and is shown as follows. ei P(f) = (N) S1 f 1 - 530 515KHz S/ f 15 545KHz 10 otherwise We want to record this signal by passing it through an analog to digital converter (ADC) with sampling rate of 100 KHz. Will there be an overlap? Why is that? If there is an overlap, what should be the minimum sampling rate...
Question 1 If we need to have a frequency resolution of 50 Hz or better and a time resolution of 10 microsecond or better, and we want the number of data points to be a power of 2, what is the minimum number of data points necessary for a Discrete Fourier Transform of a signal? What is the resulting sampling and Nyquist frequency? (9 pts) If we need to have a frequency resolution of 50 Hz or better and a...
