Opamp selected should have open-loop gain of 5 to 10 times datashheet gain at resonance. For high pass, take output from first opamp; for bandpass, take output from second opamp. 2n3460 justments are almost perfectly noninteracting if 2b4360 in sequence given. Use R2A to trim bandwidth to exactly 0. Can also serve as test transmitter putting out up to 20 mW.
View full Circuit Diagram Comments Reading Frequency range is to Hz, and FM bandwidth of error-voltage output is 20 Hz. Starting is reliable and stability is good.
Quartz crystal should be cut for operation in series-resonant mode. Pins 5 and 1 must be connected together for proper operation. L1 is 9 tums No. Article gives design theory and covers many other types of notch filters.
Both outputs have DC continuity. Variable Q feature is controlled by single passive RC network. Q1 can be 2N or T1M Q is changed by varying ratio of input and feedback resistors while keeping their product constant. Adjust 1K pot for reliable start-up and symmetrical square-wave output. 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.

Some plated crystals will work better than others in this vatasheet third-overtone types operating on their fundamental generally give best results. Adiust resistor values to tune centerfrequency. Van Dalsen, Need an Active Filter? L1 trims crystal frequency. Article covers theory of operation. 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.
Gain is fixed at -2Q2, where Q is reciprocal of damping d and ranges from less than 1 to above If R9 is advanced far enough with switch set to pass, circuit will oscllate and give sine-wave output at tuned frequency. Altemative opamps can be and Finally, trim center datasheeh to exactly 1. Sams, Indianapolis, IN,p Circuit values are for 1 MHz, but tuned circult can be adjusted 2j4360 other desired frequency.
P-Channel JFET Transistor, Gen Purpose Amp 40V 10mA – NTE
When signal goes outside tracking range, circuit sweeps between low- and high-frequency limits until suitable signal reappears. For Q of 3, feedback resistor should be 36 times value of input resistor. Resistor across crustal prevents oscillation at undesired modes. Center frequency of notch filter is about 4. DC output of low-pass terminal equals DC input plus offset voltages of both opamps.
Opamp can be one section of OPFY. Value datashest input resistor is 10K 10, ohms when gain K is 1. DC output of high-pass terminal is equal to offset voltage of integrator.
Table gives values of R1 and C1 for three different values of Q.
With minor modifications, same circuit can be used for and kHz crystals. Circuit is basically voltage-controlled bandpass filter using Optical Electronics active filter with analog multipliers.
Use series-resonant crystal having pF series capacitance. 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. For datsaheet high-pass filter, transpose positions of resistors and capacitors.
Dynamic output impedance of both outputs is less than 1 ohm. Damping is in range ofwith critical value of 1. By adding single-transistor stage, oscillator can be used as clock generator for TTL circuits. Diodes are 1N34A or 1N
