Van Dalsen, Need an Active Filter? Oscillator uses two stages, one oporating in class A and the other operating as limiter that also serves as feedback path. Q is changed by varying ratio of input and feedback resistors while keeping their product constant. Pins 5 and 1 must be connected together for proper operation.

Maximum selectivity, conesponding to maximum height of pass curve or depth of reject curve and minimum width 24360 either curve, is obtained when R9 is set for maximum gain in FET Q4. DC output of high-pass terminal is equal to offset voltage of integrator.
Circuit is basically voltage-controlled bandpass filter using Optical Electronics active filter with analog multipliers. Some plated crystals will work better than others in this circuit; third-overtone types operating on their fundamental generally give best results. By adding single-transistor stage, oscillator can be used as clock generator for TTL circuits. View full Circuit Diagram Comments Reading 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.
L1 trims crystal frequency. Finally, trim center frequency to exactly 1.
For Q of 3, feedback resistor should be 36 times value of input resistor. Dataasheet also serve as test transmitter putting out up to 20 mW. Resistor across crustal prevents oscillation at undesired modes. Gimmick is 1 or 2 turns of insulated wire wrapped around output lead.
Opamp selected should have open-loop gain of 5 to 10 times required gain at resonance. Ad justments are almost perfectly noninteracting if made in sequence given. Article gives design theory and covers many other types of notch filters. DC output of low-pass terminal equals DC input plus offset voltages of both opamps.
Altemative opamps can be and Diodes are 1N34A or 1N Use series-resonant crystal having pF series capacitance. Quartz crystal should be cut for operation in series-resonant mode. When signal goes outside tracking 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.

Center frequency of notch filter is about 4. Opamp can be one section of OPFY. Gain is fixed at -2Q2, where Q is reciprocal of damping d and ranges fatasheet less than 1 to above Dynamic output impedance of both outputs is less than 1 ohm. Sams, Indianapolis, IN,p Value of input resistor is 10K 10, ohms when gain K is 1. Starting is reliable and stability is good. For high pass, take output from first opamp; for bandpass, take datashset from second opamp. Adjust 1K pot for reliable start-up and symmetrical square-wave output.
If R9 is advanced far enough with switch set to pass, circuit will oscllate and give sine-wave output at tuned frequency. Table gives values datashheet R1 and C1 for three different values of Q.

Circuit values are for 1 MHz, but tuned circult can be adjusted to other desired frequency. Variable Q feature is controlled by single passive RC network. Damping is in range ofwith critical value of 1.
Both outputs have DC continuity. With minor modifications, same circuit can be used for and kHz crystals. Adiust resistor values to tune centerfrequency. L1 is 9 tums No. Article covers theory of operation. For equivalent high-pass filter, transpose positions of resistors and capacitors.
