L1 trims crystal frequency. Resistor across crustal prevents oscillation at undesired modes. Starting is reliable and stability is good. View full Circuit Diagram Comments Reading Opamp selected should have open-loop gain of 5 to 10 times required gain at resonance. Adiust resistor values to tune centerfrequency. Van Dalsen, Need datzsheet Active Filter? Can also serve as test transmitter putting out up to 20 mW. L1 is 9 tums No.
Damping is in range ofwith critical value of 1. For high pass, take output from first opamp; for bandpass, take output from second opamp. Value of input resistor is datashwet 10, ohms when gain K is 1.
Sams, Indianapolis, IN,p Use R2A to trim bandwidth to exactly 0.

Finally, trim center frequency to exactly 1. Ad justments are almost perfectly noninteracting if made in sequence given. Altemative opamps can be and Circuit values are for 1 MHz, but tuned circult can be adjusted to other desired frequency. Q1 can be 2N or T1M Opamp can be one section of OPFY. For equivalent high-pass filter, transpose positions of resistors and capacitors. Variable Q feature is controlled by single passive RC network.
Center frequency of notch filter is about 4.

Table gives values of R1 and C1 for three different values of Q. 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 for maximum gain in FET Q4. 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 n24360 frequency content above 10 Hz to upper frequency limit approaching 10 MHz datashwet opamp used.
Dynamic output impedance of both outputs is less than 1 ohm. Both outputs have DC continuity. DC output of high-pass terminal is equal to offset voltage of integrator. DC output of low-pass terminal equals DC input plus offset voltages of both opamps.
Use series-resonant crystal having pF series capacitance. Adjust 1K pot for reliable start-up and symmetrical square-wave output. Diodes are 1N34A 2h4360 1N Gimmick is 1 or 2 turns of insulated wire wrapped around output lead. Oscillator uses two stages, one oporating in class A and the other operating as limiter that also serves as feedback path.

Pins 5 and 1 must be connected together for proper operation. Quartz crystal should be cut for operation in series-resonant mode. With minor modifications, same circuit can be used for and kHz crystals. By adding single-transistor stage, oscillator can dattasheet used as clock generator for TTL circuits. Some plated crystals will work better than others in this circuit; third-overtone types operating on their fundamental generally give best results.
Article covers theory of operation. 2n43360 gives design theory and covers many other types of notch filters. When signal goes outside tracking range, circuit sweeps between low- and high-frequency limits until suitable signal reappears.
Circuit is basically voltage-controlled bandpass filter using Optical Electronics active filter with analog multipliers. Frequency range is to Hz, and FM bandwidth of error-voltage output is 20 Hz. Gain datasbeet fixed at -2Q2, where Q is reciprocal of damping d and ranges from less than 1 to above Q is changed by varying ratio of input and feedback resistors while keeping their product constant.
For Q of 3, feedback resistor should dayasheet 36 times value of input resistor.
