NC109 Notch Filter

The Model NC109 is a high stability, audio notch filter and is designed to suppress a single frequency and pass all others. The NC109 is used where it is desired to reject a single tone from modulating a transmitter during the presence of voice and other tones in a voice plus tone control system. The NC109 comes in three versions: The NC109-A for high frequency formats (800Hz - 3000Hz), the NC109-B for low frequency formats (280Hz - 1500Hz), and the NC109-C for extremely low frequency formats (67-250Hz).

FEATURES:
Size: 0.92"W x 1.12":L x 0.185"H

Field tunable over its frequency range
Immunity to RF
Low current drain
12" colored flying leads
High stability to prevent drift
Selectable output impedance
Operating voltage 6VDC to 24VDC
Voltage regulated circuitry

NC110 Band Pass Filter

The Model NC110 is a high stability audio band pass filter and is designed to pass a narrow band of frequencies and reject all others. The NC110 is used where it is desired to isolate a tone for decoding during the presence of voice and other tones on a voice plus tone control system. The NC110 comes in three versions: The NC110-A for high frequency formats (800Hz - 3000Hz), the NC110-B for low frequency formats (280Hz - 1500Hz), and the NC110-C for extremely low frequency formats (67Hz-250Hz).

FEATURES:
Size: 1.06"W x 1.15"L x 0.45"H

Field tunable over its frequency range
Immunity to RF
Low current drain
12" flying colored leads
High stability to prevent drift
Selectable output impedance
Operating voltage 5.5VDC to 24VDC
Voltage regulated circuitry
