Krohn-Hite Tunable Active Filters are 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 Filters provide a combination of reliability, performance and economy in bench top and remotely controlled models. Each filter is complete with a power supply, display interface for ease of use, a digital controller and a key pad for entry of functions, gains and cutoff frequency. Krohn-Hite Filter/Amplifier Systems provide a combination of flexibility, reliability and performance. There are two system chassis to choose from. A five (5) slot chassis and a sixteen (16) slot chassis. Each chassis will house a number of different filter, amplifier and filter/amplifier cards covering the frequency range from 0.03Hz to 25.6MHz. Jump
