1.	Which machines CMRR is of order of 100-120 dB?(a) VCG(b) PCG(c) EEG(d) ECGThe question was posed to me during an interview.The above asked question is from System Concepts in section Patient Monitoring System of Biomedical Instrumentation
Answer» Right option is (d) ECG The best I can EXPLAIN: CMRR of the order of 100–120 dB with 5 kW unbalance in the leads is a DESIRABLE feature of ECG MACHINES. In addition to this, under specially adverse circumstances, it becomes necessary to INCLUDE a notch filter TUNED to 50 Hz to reject hum due to power mains.
