1.	The scan-along polygonal approximation and the amplitude zone time epoch coding are the examples of the __________ category of ECG compression techniques.(a) Transformation domain(b) Time domain(c) Parameter extraction(d) Frequency domainThe question was asked in an interview for internship.The doubt is from Central Monitors topic in section Patient Monitoring System of Biomedical Instrumentation
Answer» Correct choice is (b) Time domain For explanation: In the time domain CATEGORY, the compression technique is applied DIRECTLY to the samples of the ECG signal in the time domain to REMOVE redundant information. Examples INCLUDE the scan-along polygonal approximation and the amplitude ZONE time epoch coding.
