<p>The analyzer has a resolution filter (2) with multiple pre-filters (22) including impulse values of different time durations for simultaneously measuring entire frequency regions or partial frequency regions of input signals (a-t) to be measured with different resolution bandwidths. The impulse values are independent of sweep speeds of the analyzer. The pre-filters are arranged in a row or parallely, where output of the filters are connected to associated correlator (23) using an associated analog to digital converter.</p> |
