Manual PDF
3 stages of signal processing: - answer-1. Analog to Digital Conversion
2. Signal Processor
3. Digital to Analog Conversion
digital signal processing advantages: - answer-flexibility
reproducibility
reliability- does not deteriorate with age
complexity- speech/image recognition
3 building blocks of biomedical systems: - answer-1. acquisition (analog-->digital)
2. pre-processing (filtering & artifact removal)
3. post-processing (feature extraction/classification)
2 metrics used to describe a signal: - answer-1. time/frequency
2. amplitude
__________ signals can be represented by a mathematical model - answer-deterministic
1
, __________ signals can be described by statistical properties - answer-random
Identification of ______ in random signals and ______ in aperiodic signals is goal of signal
processing - answer-deterministic segments, periodicity

answer-magnetic field, biomagnetism
two main processes involved in A/D conversion: - answer-sampling, quantization
Nyquist Theorem states that the minimum sampling rate must be: - answer-2x max frequency
___________ happens when a signal is not sampled at high enough rate - answer-aliasing
difference between analog output and digital output of quantizer: - answer-quantization error
