Our general purpose Tunable Active Filters are analog signal conditioning, frequency discriminating instruments whose signal transmission characteristics are functions of frequency. Their basic function is to pass wanted signals and suppress unwanted signals, according to frequency. Krohn-Hite provides a combination of reliability, performance and economy in these bench top models.
