METHOD AND MEASURING DEVICE FOR MEASURING THE SPECTRA IN ADJACENT CHANNELS |
摘要 |
A measuring device (1), for measuring the spectrum of a measured signal in several neighbouring channels (15-9-159) of a working channel (14), comprises a selective filter (9) which damps the working channel (14) more strongly than the neighbouring channels (15-9-159). Furthermore an analogue/digital converter (5) is provided which detects the filtered measured signal from all the channels to be measured (15-9-159, 14) in a parallel and broadband manner and converts the above to a digital signal. An equaliser (11) in series with the analogue/digital converter (5), equalises the digital signal with a frequency response which is the reciprocal of the frequency response of the selective filter (9). |
