Pins 5 and 1 must be connected together for proper operation. Oscillator uses two stages, one oporating in class A and the other operating as limiter that also serves as feedback path. When signal goes outside tracking range, circuit sweeps between low- and high-frequency limits until suitable signal reappears.
Use R2A to trim bandwidth to exactly 0. Article gives design theory and covers many other types of notch filters. For equivalent high-pass filter, transpose positions of resistors and capacitors.
B57150K1242J000 – NTC thermistors for temperature measurement
Gain is fixed at -2Q2, where Q is reciprocal of damping d and ranges from less than 1 to above DC output of high-pass terminal is equal to offset voltage of integrator. Some plated crystals will work better than others in this circuit; third-overtone types operating on their fundamental generally give best results. Adjust 1K pot for reliable start-up and symmetrical square-wave dxtasheet.
Van Dalsen, Need an Active Filter? Both outputs have DC continuity. Frequency range is to Hz, and FM bandwidth of error-voltage output is 20 Hz.
Finally, trim center frequency to exactly 1.
DC output of low-pass terminal equals DC input plus offset voltages of both opamps. View full Circuit Diagram Comments Reading Circuit values are for 1 MHz, but tuned circult can be adjusted to other desired frequency. Value of input resistor is 10K 10, dataeheet when gain K is 1.

Can also serve as test transmitter putting out up to 20 mW. Daatsheet is in range ofwith critical value of 1. With minor modifications, same circuit can be used for and kHz crystals. Gimmick is 1 or 2 turns of insulated wire wrapped around 22n4360 lead. 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. Opamp selected should have open-loop gain of 5 to 10 times required gain at resonance.
Sams, Indianapolis, IN,p Q1 can be 2N or T1M Opamp can be one section of OPFY. Circuit is basically voltage-controlled bandpass filter using Optical Electronics active filter with analog multipliers.
Variable Q feature is controlled by single passive RC network. Quartz crystal should be cut for operation in series-resonant mode. L1 is 9 tums No. Center frequency of notch filter is about 4. For high pass, take output from first opamp; for bandpass, take output from second opamp. If R9 is advanced far enough with switch set to pass, circuit will oscllate and give sine-wave output at tuned frequency.
Resistor across crustal prevents oscillation at undesired modes.
