Every decibel (dB) of transmit-power loss directly affects the quality of received data. ... PM is essentially a linear up-conversion while demodulation is a linear down-conversion. The input modulation spectrum display at baseband should provide the same spectrum display centered on the RF carrier frequency. The receiver intermediate frequency ...

The two correction factors enable the conversion of the peak power at the filter input to the peak power or average power at the output. These correction factors cover the case where the peak input power is stated in dB relative to a reference power (e.g., dBW). ... For many applications of the linear swept frequency analysis, the peak and/or ...

The human ear is more sensitive to frequencies between 1000 Hz and 5000 Hz and is less sensitive to frequencies above and below this range. Therefore the A-Weighted scale accentuates this range. A set of correction factors is used to convert from the linear decibel scale to the A-Weighted scale. The following is used for this conversion:
