It is well known that the Fourier Transform (FT) has currently a key role in signal processing applications.
The FT is useful for frequency domain analysis of a signal, i.e. it transposes a signal from time domain into
frequency domain. Many application ranging from telecommunication, electric energy distribution systems, fail
prevention analysis and general signal processing use this transform as a tool for coding/decoding or spectrum
analysis of a signal. Because of the complexity of the processing algorithm of FT and its importance in signal
analysis, many people have been working on methods and application specific processor architecture for improving
the computation performance. To get that performance improvement, efforts have been done in two directions
mainly. One related to the algorithmic point of view[1,2,3], and the other based on ASIP architecture[2,4,5,6]. The
last one was pushed by VLSI technology evolution.
In this work, we present an architecture of a processor to perform FT analysis employing a datapath with
bit-serial and digit-serial integer operation. The objective of this work was get an area efficient architecture that
could be used as a co-processor with built in all resources necessary for an embedded application. Also, we guide our
design to have a simple input / output interface. The main difference between the architecture presented here and the
others rely on the usage of a datapath bit and digit serial oriented to process each butterfly highly parallel.
This paper is organized as follows. Section 2 provides a review of FT computation. Section 3 discusses the
proposed architecture, while section 4 presents some results, followed by conclusions and future work.

Need of fft?
FT is needed for spectrum analysis, FFT is fast FT meaning it is used to obtain spectrum of a signal quickly, the FFT algorithm inherently is fast algorithm than the conventional FT algorithm
How can I use Python to plot the Fast Fourier Transform (FFT) of a signal?
To plot the Fast Fourier Transform (FFT) of a signal using Python, you can use the numpy library to compute the FFT and the matplotlib library to plot the results. First, import the necessary libraries: python import numpy as np import matplotlib.pyplot as plt Next, generate a sample signal and its corresponding time values: python Generate a sample signal fs 1000 Sampling frequency t np.arange(0, 1, 1/fs) Time values signal np.sin(2 np.pi 50 t) 0.5 np.sin(2 np.pi 120 t) Example signal Then, compute the FFT of the signal using np.fft.fft: python fftresult np.fft.fft(signal) freqs np.fft.fftfreq(len(signal), 1/fs) Finally, plot the FFT magnitude spectrum using plt.plot: python plt.figure() plt.plot(freqs:len(freqs)//2, np.abs(fftresult):len(freqs)//2) plt.xlabel('Frequency (Hz)') plt.ylabel('Magnitude') plt.title('FFT of Signal') plt.show() This code snippet demonstrates how to use Python to plot the FFT of a signal.
Whatpart of the computer determines the maximum processor speed?
nothing to do with the computer, its the processor the determines that (u can get processor upgrades)
What types of transfers must a computers interconnection structure (bus) support?
The Type of transfers that must a computer interconnection structure support thats a bus is the following: (1) Memory to Processor (2) Processor to Memory (3) I/O to Processor (4) Processor to I/O (5) I/O to or from Memory
What part of the computer determines the maximum processor speed?
The processor (obviously)
What are there advantages and where are there used fft?
because they have a high speed compared to fft
What are there advantages and where are there used?
FFT reduces the computation since no. of complex multiplications required in FFT are N/2(log2N). FFT is used to compute discrete Fourier transform.
How do you plot frequency spectrum using fft function in MATLAB?
plot(abs(fft(vectorname)))the FFT function returns a complex vector thus when you plot it, you get a complex graph. If you plot the absolute value of the FFT array, you will get the magnitude of the FFT.

What is the need of FFT?
There's no need for it.
What are some details about the implementation of zoom FFT in ultrasonic blood flow analysis?
Zoom FFT is a diagnostic tool for the detection of blood clots and other diseases. It is less costly than other techniques. Zoom FFT uses a low frequency to measure blood flow in order to find clots. A transmitter passes an ultrasonic wave through the blood vessels. A reflected signal is passed to a DSP processor. (This is similar to the Doppler technique.) The process is achieved with one DSP chip in order to keep the costs lower.
Why FFT is faster than DFT?
FFT is faster than DFT because no. of complex multiplication in DFT is N^2 while in FFT no. of complex multiplications are N/2(log2N). for example if N=8 no. of complex multiplications required in DFT are 64. while no. of complex multiplications required in FFT are 12 thus reduces computation time.
