What high signal?

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.

It's a ratio.

Clarity! Context! Getting blood out of a stone?

More's the pity you are not as rational as it.

What is? SNR is. Signal is not, and neither is noise. "It should be obvious the SNR will be high when the signal is high, and low when the noise is high" is junk.
