APPLICATION INFORMATION
high-Q notch filter
In general, Texas Instruments enhanced-JFET operational amplifiers serve as excellent filters. The circuit in
Figure 64 provides a narrow notch at a specific frequency. Notch filters are designed to eliminate frequencies
that are interfering with the operation of an application. For this filter, the center frequency can be calculated as:
f
O
1
2
R1
C1
With the resistors and capacitors shown in Figure 64, the center frequency is 1 kHz. C1 = C3 = C2 + 2 and
R1 = R3 = 2
×
R2. The center frequency can be modified by varying these values. When adjusting the center
frequency, ensure that the operational amplifier has sufficient gain at the frequency required.
