P-Channel JFET Transistor, Gen Purpose Amp 40V 10mA – NTE
For Q of 3, feedback resistor should be 36 times value of input resistor. Pins 5 and 1 must be connected together for proper operation. Dynamic output impedance of both outputs is less than 1 ohm. Van Dalsen, Need an Active Filter?
Diodes are 1N34A or 1N Q is changed by varying ratio of input darasheet feedback resistors while keeping their product constant. For high pass, take output from first opamp; for bandpass, take output from second opamp. L1 is 9 tums No. Opamp can be one section of OPFY. 2n436 gives values of R1 and C1 for three different values of Q.
Value of input resistor is 10K 10, ohms when gain K is 1.

Some plated crystals will work better than others in this circuit; third-overtone types operating on their fundamental generally give best results. Opamp selected should have open-loop gain of 5 to 10 times required gain at resonance. Sams, Indianapolis, IN,p DC output of low-pass terminal equals DC input plus offset voltages of both opamps. Adjust 1K pot for reliable start-up and symmetrical square-wave output. Adiust resistor values to tune centerfrequency. DC output of high-pass terminal is equal to offset voltage of integrator.
Use R2A to trim bandwidth to exactly 0. Damping is in range ofwith critical value of 1.
Quartz crystal should be cut for operation in series-resonant mode. View full Circuit Diagram Comments Reading L1 trims crystal frequency.
If R9 is advanced far enough with switch set to pass, circuit will oscllate and give sine-wave output at tuned frequency. Low-pass output contains DC to 10 Hz, and high-pass output has frequency content above 10 Hz to upper frequency limit approaching 10 MHz for opamp used.

Center frequency of notch filter is about 4. Circuit is basically voltage-controlled bandpass filter using Optical Electronics active filter with analog multipliers. When signal goes outside datssheet range, circuit sweeps between low- and high-frequency limits until suitable signal reappears.
Frequency range is to Hz, and FM bandwidth of error-voltage output is 20 Hz. Starting is reliable and stability is good. Both outputs have DC continuity. Variable Q feature is controlled by single passive RC network. Q1 can be 2N or T1M Gain is fixed at -2Q2, where Q is reciprocal of damping d and ranges from less than 1 to above Finally, trim center frequency to exactly 1. Use series-resonant vatasheet having pF series capacitance.
For equivalent high-pass filter, transpose positions of resistors and capacitors. Article covers theory of operation.
Maximum dtasheet, conesponding to maximum height of pass curve or depth of reject curve and minimum width of either curve, is obtained when R9 is set for maximum gain in FET Q4. Circuit values are for 1 MHz, but tuned circult can be 2n4306 to other desired frequency.
Article gives design theory and covers many other types of notch filters. Gimmick is 1 or 2 turns of insulated wire wrapped around output lead. Resistor across crustal prevents oscillation at undesired modes.
Altemative opamps can be and
