SUMMARY

The discussion focuses on calculating the Fast Fourier Transform (FFT) from the output of an Analog-to-Digital Converter (ADC). The primary concern is how to utilize the digital output, which consists of real values, to compute the FFT, given that FFT algorithms typically require both real and imaginary components. It is established that in this case, the imaginary part of the sampled signal is zero, simplifying the FFT calculation process.

PREREQUISITES
  • Understanding of Fast Fourier Transform (FFT) algorithms
  • Knowledge of Analog-to-Digital Converters (ADC) and their output formats
  • Familiarity with digital signal processing concepts
  • Basic programming skills for implementing FFT calculations
NEXT STEPS
  • Research the implementation of FFT algorithms in Python using libraries like NumPy
  • Explore the role of ADC in digital signal processing
  • Learn about the implications of using real-only signals in FFT calculations
  • Investigate different FFT algorithms and their performance characteristics
USEFUL FOR

Engineers, digital signal processing enthusiasts, and developers working with ADCs and FFT calculations will benefit from this discussion.

Hi All,
Its my first post here. I want to know how the digital output which comes out of an ADC can be used to calculate FFT. Because FFT algorithms usually needs real and imaginary parts of a sampled signal?

Thanks.
