It should be obvious the SNR will be high when the signal is high, and low when the noise is high.
Ummmm. Something of a lack of clarity there.
Definitions of "signal" and "noise" and even "SNR" for this context might help. A simplistic view could be that if the signal is doubled and the noise is doubled, the SNR will be unchanged. The same could be said of the SNRM.
