Biomedical signal processing

What is 'Baseline Wander'?

• It is the effect where the base axis (x-axis) of a signal appears to ‘wander’

• It is the effect where the Y-axis of a signal appears to ‘wander’

• It is the effect where the x-axis and y-axis of a signal appears to ‘wander’

What is 'Random noise'?

• Not predicted from past values

• Predicted from past values

Is random noise 'deterministic'?

• Yes

• No

How does Noise in ERP occur?

• signal obtained in response to a stimulus

• signal obtained in response to a non stimulus

What causes High frequency noise in ECG ?

• due to amplifiers or recording systems

• due to stationary x-axis

• due to stationary y-axis

• due to breathing

How does Motion artifact in ECG occur?

• Due to coughing

• Due to amplifier sound

• Stationary X-Axis

Can the filters be adaptive?

• Yes

• No

What is the purpose of median filter?

• To remove noise

• To find the median value

• To identify artifact

What is meant by artifacts?

• undesired components

• desired components

• good quality signal
