Research output: Contribution to journalArticleScientificpeer-review


A real-time spectrum analyzer based on a charge-coupled device (CCD) is described. The power spectrum is calculated by the chirp z-transforn using the CCD. The analyzer includes a buffer memory for the input data and an integrator to sum the computed spectral estimates for better statistical accuracy. The analyzer makes one 512-point, discrete Fourier Transform (DFT) for complex data in 1.024 ms.
