Filtering with math channels

PicoScope's math channels can be used to apply a sliding-window filter to your signals. All four basic shapes of filter are available:

• High-pass – rejects low-frequency hum and DC offsets
• Low-pass – removes high-frequency noise
• Band-pass – extracts a band-limited signal (such as a radio channel) from background noise
• Band-stop – (also called notch) rejects band-limited interference such as an unwanted RF signal or power-supply ripple
