The Krohn-Hite 3202 Dual Filter is a versatile and high-performance electronic filter designed for various applications in the field of signal processing. This dual filter offers a unique combination of 20 Hz high-pass (Hp) and low-pass (LP) filters, as well as a band-pass (Bp) filter, all in a single compact package.
The high-pass filter section of the Krohn-Hite 3202 allows for the attenuation of frequencies below 20 Hz, preserving and passing signals above this cutoff frequency. This is particularly useful in applications where high-frequency components are of interest, such as in audio signal processing, where low-frequency noise can be filtered out.
The low-pass filter, on the other hand, attenuates frequencies above 20 Hz, allowing for the preservation and passing of signals below this cutoff frequency. This is often used in applications where high-frequency noise or interference needs to be eliminated, such as in analog communication systems.
In addition to its high-pass and low-pass capabilities, the Krohn-Hite 3202 also includes a band-pass filter. This filter allows for the selective passage of signals within a specific frequency range, typically between the high-pass and low-pass cutoff frequencies. This is particularly useful in applications where specific frequency components need to be isolated and analyzed.
The Krohn-Hite 3202 is a manual filter, meaning the cutoff frequencies are adjustable manually using knobs or potentiometers. This gives the user fine control over the filter's characteristics, allowing for precise tuning to meet the specific requirements of the application.
The Krohn-Hite 3202 is built using high-quality components and is designed for long-term reliability and durability. It features a rugged, compact enclosure that can withstand harsh environmental conditions, making it suitable for use in a variety of applications, including industrial, military, and aerospace.
In summary, the Krohn-Hite 3202 Dual Filter is a versatile and powerful electronic filter that offers a unique combination of high-pass, low-pass, and band-pass filtering capabilities. Its manual adjustability gives the user fine control over the filter's characteristics, making it a valuable tool for a wide range of signal processing applications.

Watch for future offers. An extremely useful feature of this filter is that it contains two independently variable channels, and therefore can be configured for band-pass or band-reject operation as well permitting cascading the sections increased attenuation. The unit is presently wired for north American power, but can be rewired internally to run in UK, etc manual a copy, readable copy made by tucker complete with foldout schematic.
The other photo shows result of both filters connected in series, tuned for 600 khz, but set RC response. In both photos, a 1-volt RMS, 600 khz sine wave is the input.
Two other photos show oscilloscope captures of the unit in operation. One of the photos shows a scan some units specification from operating manual. One photo shows the output of a single section tuned to 600 khz and set for maximally flat.
This shows the maximum attenuation possible.
