Jan 31, 2009 · dbc to dbm dBm and dBc are completely different so there is no 'conversion' between the two. dBm - indicates the power measurement relative to 1 milliwatt. 0 dBm means no change from 1 mW, i.e. a power of exactly 1 mW. 3 dBm means 3 dB greater than 0 dBm. dBm is the relative difference to a fixed reference power of 1 mW.
Why do we use dBc/Hz as measurement unit? - Forum for …
Nov 26, 2006 · If you were comparing two CW tones it would be dBc. Comparing a tone to noise must be dBc/Hz. Also, it's in dB because it's easier to add than multiply. If you want to know the thermal noise power in a 1 kHz bandwidth is simply -174 dBm/Hz + 30 dBHz = -144 dBm.
How to measure SNR using Spectrum Analyzer? (dBc or dB)
Nov 7, 2020 · Since dBc means decibels relative to carrier, from the given Signal power(23.33 dBm) and SNR(58.75 dBc), you can derive Noise power which is -35.42 dBm. Then you can convert dBm to Watt which means Signal power = 215.278 mW and Noise power = 287.078 nW.

What does "dBc/Hz" mean? Help newbie please - Forum for …
Feb 27, 2007 · u have -70dBc/Hz as u have center freq,. power 20dbm/Hz and 1st comp @ -50dBm/Hz , i.e,. the hole graph is dBm/Hz or dBm/Hz but if u subtract two powers then the result is in dB/Hz and if u refered any result to the carrier then the result will be dBc/Hz
What is the relation between dB AND dBm - Forum for Electronics
Jan 2, 2008 · add db and dbm values Hello All, dB or not dB? Everything you ever wanted to know about decibels but were afraid to ask… True or false: 30 dBm + 30 dBm = 60 dBm? Why does 1% work out to be -40 dB one time but then 0.1 dB or 0.05 dB the next time? These questions sometimes leave even experienced engineers scratching their heads.

How to Convert dbc to db - Forum for Electronics
Mar 19, 2014 · lets give an example: unsigned 10 bit adc => so output is from 0 to 2^(10)-1. The maximum output value 2^(10)-1 is equall to 0 dBc. SNR is in log scale equall to Signal - Noise. Noise in dBc scale is always with '-' as it cant physically be greater then adc resolution ( max output), so SNR is always positive number.
