Filter that amplifies frequency above certain value is called ________

1.	Filter that amplifies frequency above certain value is called ___________(a) low pass filter(b) high pass filter(c) band pass filter(d) band stop filterThe question was asked during an interview for a job.I want to ask this question from Cardiac Monitor topic in portion Patient Monitoring System of Biomedical Instrumentation
Answer» Right answer is (b) HIGH pass FILTER Easy explanation: High pass filter amplifies signal above a certain frequency. LOW pass filter amplifies signals below a certain frequency. Band pass filter amplifies frequencies within a certain band. Band stop filter amplifies all the frequencies EXCEPT those in a certain band.
