Category: Oscillator Circuits / Varius Circuits Views: 3502 Rank: 0 This is a useful instrument for works hops. The standard of the produced frequencies is 10 to 1. The basic frequency is produced by a crystal with high accuracy. The circuit is consisted by the oscillator, around the crystal and the frequency divider, which divides to 10. The produced pulses are quadrangular.

Related circuits Add-On Pulse Generator Circuit This pulse generator can supplement a standalone pulse generator. Using a transistor and a 555 timer, pulse widths of 5 to 500 can be produced. The value of C3 is approximately found from the formula: C3 uF = 1.1 x10-5 T where T is the shortest pulse width (uS) desired in a 10:1 range (T... The oscillator output of the XR-567 can be amplified using the output amplifier and high-current logic output available at pin 8. In this manner, the circuit can switch 100-mA load currents without sacrificing oscillator stability. This circuit works well in the range of 50 kHz to 500 kHz. Slight component modifications are needed for higher frequency operation Quad op amp generates 4 waveforms A quad op amp can simultaneously generate four synchronized waveforms. The two comparators (Al and A3) produce square and pulse waves, while the tWo integrators (A2 and A4) give triangular and sawtooth waves. Sine-Wave/Square-Wave Converter An op amp used as a comparator produces a 10-V p-p square-wave output with 100-mV input, to 15 kHz. Adjust Butler emitter follower oscillator 100Mhz This circuit has good performance without amplifier has a gain of only one with built-in any parasitics because emitter follower negative feedback Last-cycle-completing-gated-oscillator Regenerative feedback at C enables the oscillator to complete its timing cycle, rather than immediately shutting it off. Triangle-Wave Generator Circuit This is a simple triangle-wave generator using two IC devices and a transistor. The triangle wave is used as feedback to the square-wave generator. SI allows range switching in three ranges from 100 Hz to 100 kHz.
