| Abstract: |
The final stages of receiver electronics are designed to extract information about the intensity of cosmic signals as a function of time, frequency, and polarization. The required signal processing can be as simple as a total power detector or as complex as a pulsar search machine that looks for periodic, dispersed pulse signatures in the time and frequency domain. This mini-lecture gives a brief overview of square-law detectors, FFT spectrometers, polarimeters, and pulsar processors. It touches on calibration issues and the synchronous control of front-end calibration signals and beam and load switches. |
