View full Circuit Diagram Comments Reading Oscillator uses two stages, one oporating in class A and the other operating as limiter that also serves as feedback path.

Can also serve as test transmitter putting out up to 20 dataseet. If R9 is advanced far enough with switch set to pass, circuit will oscllate and give sine-wave output at tuned frequency.

Opamp can be one section of OPFY. Gain is fixed at -2Q2, where Q is reciprocal of damping d and ranges from less than 1 to above Q1 can be 2N or T1M Circuit is basically voltage-controlled bandpass filter using Optical Electronics active filter with analog multipliers. Van Dalsen, Need an Active Filter? Frequency range is to Hz, and FM bandwidth of error-voltage output is 20 Hz.


Adjust 1K pot for reliable start-up and symmetrical square-wave output. L1 trims crystal frequency. Sams, Indianapolis, IN,p Both outputs have DC continuity. Adiust resistor values to tune centerfrequency. Quartz crystal should be cut for operation in series-resonant mode. Center frequency of notch filter is about 4. Diodes are 1N34A or 1N Pins 5 and 1 must be connected together for proper operation.

Variable Q feature is controlled by single passive RC network. Ad justments are almost perfectly noninteracting if made in sequence given. Dynamic output impedance of both outputs is less than 1 ohm. Circuit values are for 1 MHz, but tuned circult can be adjusted to other desired frequency. Gimmick is 1 or 2 turns of insulated wire wrapped around output lead.

Resistor across crustal prevents oscillation at undesired modes. 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.


With minor modifications, same circuit can be used for and kHz crystals. For Q of 3, feedback resistor should be 36 times value of input resistor. Q is changed by varying ratio of input and feedback resistors while keeping their product constant. For equivalent high-pass filter, transpose positions of resistors and capacitors.

DC output of high-pass terminal is equal to offset voltage of integrator. When signal goes outside tracking range, circuit sweeps between low- and high-frequency limits until suitable signal reappears.

Some plated crystals will work better than others in this circuit; third-overtone types operating on their fundamental generally give best results. L1 is 9 tums No.

Damping is in range ofwith critical value of 1.

Opamp selected should have open-loop gain of 5 to 10 times required gain at resonance. Article gives design theory and covers many other types of notch filters. Article covers theory of operation. Table gives values of R1 and C1 for three different values of Q.
