SUMMARY
The calculation of effective noise power spectral density involves understanding the noise factor (NF) and its impact on effective noise temperature (Te). Given a noise factor of 3, the effective noise temperature can be calculated using the formula Te = 290 K x (10 NF/10 - 1). Bandwidth (B) significantly influences noise levels, with a 1 Hz bandwidth resulting in an effective noise power of -174 dBm and a 1 kHz bandwidth yielding -144 dBm, demonstrating a 30 dB difference.
