Thank you all!
I was talking about a GE MRI scanner.
It has Analog Receiver (Gain) and Digital Receiver (gain). both ARG and DRG can be automatically determined or manually changed. If automatically determined, the values change from scan to scan. And I want to know the SNRs with different...
Thank you very much!
We have analog and digital amplifiers and can adjust the Analog Receiver Gain and DRG.
Do I understand that (1) the Analog Receiver Gain does NOT change the SNR (because the amplifier does not distinguish noise and signal)? (2) the Digital Receive Gain does not change...
Thank you very much!
Do I understand that (1) the Analog Receiver Gain does NOT change the SNR (because the amplifier does not distinguish noise and signal)? (2) the Digital Receive Gain does not change the SNR significantly if the digitization noise is NOT a problem?
Thanks!
Dear all,
I have questions regarding to the relations betw SNR and receiver gains (digital and analog):
We have a system that allows us to set the analog receiver gain (ARG) and digital receiver gain (DRG). The signal doubles if we increase one integer of either ARG or DRG (eg from 12 to...
