For this project, I was more interested in producing a clean undistorted sinewave rather than pushing it to the limits in terms of frequency. Thus, only a frequency ratio of 1 was chosen toso a dataasheet adjustment is possible.

FM would also be good for testing a phase-locked loop.

The frequency must be adjustable and dayasheet least cover the low frequency range. Feed Y and the XR with a triangle wave, and X by the rectified voltage across the tuned circuit.

It can be connected to any type of datazheet audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.

The sample design renounces everything that is not absolutely necessary.

The formula for the frequency is shown in the figure. The output waveforms can be both amplitude and frequency modulated.

XR2206 Function Generator

The kHz iv could be picked up on an AM radio at the expected frequency, and the modulation heard. Function Generator with XR If the applied voltage V is 3. The output was centered on 6. The circuit includes an auto ranging as well as reset switch and produces very accurate and stable readings.

On the board, the outputs of the circuit were placed in small wire loops, where the signals can be picked up directly with datasehet clips. With the component values shown above, the overlapping frequency ranges are shown in the following table: The frequency is changed by using a variable resistor.

This LC Meter allows to measure incredibly small inductances making it perfect tool for making all types of RF coils and inductors.

The amplitude setting at pin 3 is connected with fixed resistors, so the output voltage is always the same. It also analyzes transistor’s characteristics such as voltage and gain. Supply VC from a function generator, setting the DC bias at 3. R is the normal timing resisor, while RC handles the modulating current.

The additional output at pin 11 also delivers a square wave with the same frequency. It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc.

It is a very useful bench test equipment for testing and finding out the frequency of various devices with unknown frequency such as oscillators, radio receivers, transmitters, function generators, crystals, etc. The output waveforms can be both amplitude and frequency modulated. With a pot of 2 megohms and a fixed resistor of 1 kOhm variation gives a ratio of 1 to and may include a range of 10 Hz to 20 kHz sweep. The meter is a perfect addition to any power supply, battery chargers and other electronic projects where voltage and current must be monitored.

An increase in V lowers the frequency, and an increase raises it. The output can be buffered to adjust its DC component and signal amplitude. A sine-shaping network makes the triangular signal of the VCO, a sinusoidal signal that can be picked up at the pin 2.

This gives easy frequency-shift keying FSK by a logic input to pin 9. The 50k pot adjustment is also important. There are integrated circuits that produce sine waves, although they are really relaxation oscillators and the sine waves come from shaping a triangle wave. One could make a small AM radio transmitter with this chip for use over short distances.

At pin 3 to set the exact medium voltage and the output amplitude. When pin 9 is below 0. The capacitor C and the power to determine the frequency at pin 7. Switching frequency ranges from about one switch Verification of a frequency scale Setting the output voltage through a second potentiometer Adjustment to minimize distortion of the sinusoidal signal Setting of the symmetry of the triangular signal 1Hz – 2MHz XR Function Generator Kit.

The XR offers many possibilities for sine wave generation and modulation over a wide range of frequency. Frequency can be varied by a range switch and a potentiometer, so that one could make a fairly useful function generator based on this chip, at low cost.

The XR has an AM input at pin 1. The proper adjustment of these controls is necessary for a good-looking sine wave. But there are some points that could improve it take to build an almost professional function generator.

Use a buffered potentiometer to test the dependence of frequency on VC. Frequency control The frequency range is controlled with the timing capacitor connected between pins 5 and 6 of the XR and the timing resistors VR1, VR2 and R2 conencted in series between pin 7 and v. One is displaying frequency response on the scope–you might try this with a parallel resonant circuit.

It can be connected to any type of stereo audio source such as iPod, Computer, Laptop, CD Player, Walkman, Television, Satellite Receiver, Tape Deck or other stereo system to transmit stereo sound with excellent clarity throughout your home, office, yard or camp ground.

Function Generator with XR2206

A common function generator provides sine, for example, triangular and square waves. You can control lights, fans, AC system, computer, printer, amplifier, robots, garage door, security systems, motor-driven curtains, motorized window blinds, door locks, sprinklers, motorized projection screens and anything else you can think of.

This circuit sets the average value of the output waveform here to 6. Although neither chip is in current production, both are still widely available – either as old datashet or, perhaps, as ‘clones’.

It’s small, power efficient, yet customizable through onboard 2 x 7 perfboard that can be used for connecting various sensors and connectors.
