Category: Oscillator Circuits / Varius Circuits Views: 785 Rank: 0 The Tri-Waveform Generator can be used for a number of different uses. The one that I use it for is a signal generator to test circuits. The frequency range is 20 to 20khz. and can be adjusted by R1. The duty cycle or the time that the waveform is high and the time that the waveform is low can be adjusted by R4. The purpose of R2 and R3 are to clean up any distortion on the sine wave output. To do this you must hook up the sine wave output to and oscilloscope and adjust R2 & R3 to make the sine wave as accurate as possible. visit page. 
Related circuits Clock-Driven Triangle-Wave Generator Circuit U2-a, 03 and R2 operate as an integrator. Q2 and Q3 are alternately switched at 256 cycles. The XR-567 functions as a precision oscillator with two separate square-wave outputs at pins 5 and 8, that are at nearly quadrature phase with each other. Here exist a small collection from three generators, what using crystal for basic production of oscillations. Each generator uses different topology of circuit for the production of oscillations. Two CA3130's are used, one as a multivibrator and the other as a hysteresis switch. The third amplifier, a CA3160, is used as a linear staircase generator. The swept-frequency oscillator offers an inexpensive source of discrete frequencies for use in testing digital circuits. In this configuration, the circuit generates an 80-second seguence of eight frequencies, dwelling for 10 seconds on each frequency. You can change the dwell time or the... An output pulse"s characteristics depend upon two multivibrator"s timing components. IC1"s freerunning astable-mode frequency sets the pulse"s prf, Intended primarily as a building block for a QRI"transmitter, this 20-MHz oscillator delivered a clean 6-V, This low-cost operational-amplifier circuit (A) generates four different functions with adjustable periods. For the components shown here, the period of the output waveforms is given by T = 4RC and T = 2RC.
