... (medium performance) and 60 dB (high performance), as shown in Fig. 3-4b and 3-4c. One satisfactory approach is shown in Fig. 3-4b, where the passband center frequencies are increased sufÞciently. In some ... dBm (1.0 mW) in a 1.0-Hz band, which is 10.0 W in the 10-kHz passband. The scanning instrument has a noise bandwidth of 300 Hz, so the passband noise power in that bandwidth is watts...
