2009年1月31日 · 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.

2006年11月26日 · 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.

2020年11月7日 · 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.

2007年2月25日 · 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

2022年7月4日 · IM3[dBc] VS Pout[dBm] Does work well on IM3[dBc] VS Pin(dBm), but IM3[dBc] VS Pout/(dBm) not working, I haven't been able to get this formula to work in any way.

2008年1月2日 · 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.

2014年3月19日 · 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.

2013年5月23日 · Dear all, Could anyone teach me how to convert noise value in V/sqrt Hz into dB? For example, if i have input noise= 9.758mV/sqrt Hz and output noise= 156.2pV/sqrt Hz, the bandwidth (cutoff freq)= 1.4354MHz, Then how i can convert the …
