Reply Upvote. can asy make one much cheaper with a waveform generator ICL IT GIVE. The ICL is a function generator chip, capable of generating triangular, square, sine, pulse and sawtooth waveforms. From this sine, square.

Determine the range of modulation indices and modulating frequencies at which this circuit will operate. Confirm your obervations with theoretical predictions. Experiment with feeding in multi-tone modulating signals at the modulating signal input of this circuit.

Use the slope detector circuit you have designed in Part A to recover the baseband signal for both single- and multi-tone. Observe and listen.

Low Cost Waveform Generator (0 - 20MHz)

Part 3 The obective is to generate an FM signal using a voltage controlled oscillator and observe the waveforms in the time and spectral domains.

Design the test circuit shown in Figure 3.

Test the circuit by feeding in an FM signal from the arbitrary function generator, observe waveform and spectrum and listen to the audio output. Vary the input signal amplitude, the modulating signal frequency and the modulation index.

Experiment with the capture range and lock range of the PLL. When does the demodulator fail to detect the message signal?

Link the modulator-demodulator circuits and observe signal progression from input to output. Function Generator, generate an FM wave with carrier frequency of 30kHz and modulation frequency 1kHz single tone.

Step 2: Over View

Compare with the pure tone of the same frequency. Part 2 The objective in Part 2 is to generate single- and multi-tone FM signals using a voltage controlled oscillator and observe the waveforms in the time and spectral domains. The output of the VCO when no modulation is applied i.

Design the circuit for a carrier frequency of 30 kHz. Test the system response by feeding a 1Hz audio-frequency tone to the FM sweep input pin. Observe the waveforms on the oscilloscope.

Figure 2: Frequency modulation application circuit from ICL data-sheet. Oberve the input and output waveforms. Confirm your obervations with theoretical predictions.

Once the symmetry is good across the frequency range of the audio generator, R21 is used to trim the distortion of the sine wave to the lowest possible level. The calibration is more or less an "around the horn" affair - one has to go back and forth a few times between trimpots before everything is set.

An oscilloscope is pretty much required for setting symmetry of the waveforms.

Distortion may be set by that most precise piece of equipment you possess the set of ears you have placed on each side of your head , or an oscilloscope, or a combination of the two. Frequency may be set with a counter, though I personally used an oscilloscope when I had it on the bench as my counter has been defunct for some time.

Go back and forth between these two pots until you get good symmetry at the low and high ends. Turn R25 Coarse and R26 Fine to their highest settings. While monitoring the output on a frequency counter, adjust trimmer R10 Max to give 20 kHz.

Turn R25 and R26 to their lowest settings.

Adjust R23 Min to give 20 Hz. Go back and forth between these to pots to arrive at a solid 20 Hz to 20 KHz range. While listening to the sine output and watching it on a scope, adjust R21 Sine Distortion Trim for minimal harmonic distortion.

This is easy to do with ears alone. Repeat the entire sequence a couple times to lock in all trimmers as desired.For example, a cold circuit set to kHz, decreases its frequency by about kHz after warming up. When does the demodulator fail to detect the message signal?

Digitally capture samples of the input and output waveforms in this range Perform a spectral analysis of these input and output waveforms. Minimum number of external parts required No input bootstrap capacitor required. Additionally In my version of device i added the input mode for the meter, which can be selected on the range switch, and the output connector can be used to measure external signals.
