Adjust 1K pot for reliable start-up and symmetrical square-wave output. Ad justments are almost perfectly noninteracting if made in sequence given. L1 trims crystal frequency. Use series-resonant crystal having pF series capacitance. When signal goes outside tracking range, circuit sweeps between low- and high-frequency limits until suitable signal reappears.
Some plated 24360 will work better than others in this circuit; third-overtone types operating on their fundamental generally give best results. Frequency range is to Hz, and FM bandwidth of error-voltage output is 20 Hz. Opamp selected vatasheet have open-loop gain of 5 to 10 times required gain at resonance. Center frequency of notch filter is about 4.
Starting is reliable and stability is good. Circuit is basically voltage-controlled bandpass filter using Optical Electronics active datashert with analog multipliers. Opamp can be one section of OPFY.
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.

DC output of low-pass terminal equals DC input plus offset voltages of both opamps. Variable Q feature is datazheet by single passive RC network. Sams, Indianapolis, IN,p Table gives values of R1 and C1 for three different values of Q.
Quartz crystal should be cut for operation in series-resonant mode. For Q of 3, feedback resistor should be 36 ddatasheet value of input resistor. Circuit values are for 1 MHz, but tuned circult can be adjusted to other desired frequency.

Resistor across crustal prevents oscillation at undesired modes. L1 is 9 tums No. For high pass, take output from first opamp; for bandpass, take output from second opamp. Use R2A to trim bandwidth to exactly 0. Can also serve as test transmitter putting out up to 20 mW. Datashwet covers theory of operation. Altemative opamps can be and Adiust resistor values to tune centerfrequency.
Q1 can be 2N or T1M Both outputs have DC continuity. Value of input resistor is 10K 10, ohms when gain K is 1.

Damping is in range ofwith critical value of 1. Maximum selectivity, conesponding to maximum height of pass curve or depth of reject curve and minimum width of either curve, is obtained when R9 is set datsaheet maximum gain in FET Q4. Van Dalsen, Need an Active Filter? If R9 is advanced far enough with switch set to pass, circuit will oscllate and give sine-wave output at tuned frequency.
DC output of high-pass terminal is equal to 2n4306 voltage of integrator. Gain is fixed at -2Q2, where Q is reciprocal of damping d and datasheeet from less than 1 to above Dynamic output impedance of both outputs is less than 1 ohm.
Pins 5 and 1 must be connected together for proper operation. Article gives design theory and covers many other types of notch filters. With minor modifications, same circuit can be used for and kHz crystals.
Diodes are 1N34A or 1N Q is changed by varying ratio of input and feedback resistors while keeping their product constant. Gimmick is 1 or 2 turns of insulated wire wrapped around output lead.
Oscillator uses two stages, one oporating datassheet class A and the other operating as limiter that also serves as feedback path.
Dataxheet, trim center frequency to exactly 1. View full Circuit Diagram Comments Reading For equivalent high-pass filter, transpose positions of resistors and capacitors. By adding single-transistor stage, oscillator can be used as clock generator for TTL circuits.
