美國KROHN-HITE 3988濾波器，KH3988濾波器
美國KROHN-HITE 3988濾波器規格 ?? ?

Krohn-Hite 3988 Butterworth / Bessel雙通道濾波器是仔細設計的濾波器系列之一，提供易于操作，可靠性性高。

KH3988濾波器在低通模式下提供0.03Hz至1MHz的可調諧頻率范圍，在高通模式下提供0.03Hz至300kHz的可調諧頻率范圍。這兩種模式都可以通過002選項擴展到0.003Hz。頻率響應特性在頻域中進行干凈濾波，或者線性相位（Bessel）可以最大限度地平坦（Butterworth），以提供卓越的脈沖濾波。
KH3988濾波器的每個通道是8極，寬范圍，低通/高通濾波器或放大器，以0.1dB的步長提供70dB的增益。KH3988濾波器將接收0dB增益的 10V峰值的輸入信號，并具有可選擇的交流或直流耦合。過載檢測器是標準配置，可幫助用戶檢測輸入信號或不正確的增益設置。用于存儲前面板設置的九十九組非易失性存儲器存儲在電池支持的CMOS中，可以通過簡單的命令調用。

DESCRIPTION of KROHN-HITE 3988
The Krohn-Hite Model 3988 Butterworth/Bessel dual channel
filter is one of a family of filters carefully designed with the user in
mind, providing ease of operation, reliability and price

competitiveness.
The 3988 provides a tunable frequency range from 0.03Hz to
1MHz in the low-pass mode and 0.03Hz to 300kHz in the
high-pass mode. Both modes are extended down to 0.003Hz with
the 002 option. The frequency response characteristic is either
maximally flat (Butterworth) for clean filtering in the frequency
domain, or linear phase (Bessel) to provide superior pulse
filtering.
Each channel of the 3988 is an 8-pole, wide range,
low-pass/high-pass filter or an amplifier providing gains to 70dB
in 0.1dB steps. The 3988 will accept input signals of ?10V peak at
0dB gain and has selectable ac or dc coupling. Overload detectors
are standard and assist the user in detecting input signals or
incorrect gain settings. Ninety-nine groups of non-volatile
memory for storage of front panel set-ups are stored in
battery-backed CMOS which can be recalled with a simple
command.
BAND-PASS/BAND-REJECT OPERATION
With the Model 3988, the user can simply connect two channels in
series to achieve band-pass operation or two in summed parallel

for band-reject operation.
APPLICATIONS
Applications for the 3988 are ultra-sound measurements, random
noise testing, sound recording, suppressing interference in audio
communications and related fields of medical, geological,
geophysical, oceanographic, military and more. All these features
and more are backed with the quality Krohn-Hite has provided in
filters since 1949.
