NCH TONE GENERATOR SOFTWARE
Tone Generator Audio Test Tone Generator
Create audio test tones on Windows or Mac
Tone Generator is a sine wave generator, frequency generator and signal generator that lets you create audio test tones, sweeps or noise waveforms using your computer or a PDA handheld. The full features list of this tone generator software follows but if you have any doubt about its suitability a quick way to test it is to simply download and install it. You don't need to purchase to download and it only takes a couple of minutes to complete.
Typical Applications
Generation of test tones in radio and other studios for the alignment of levels.
Calibration and testing of audio equipment or speakers.
Tuning music instruments as an accurate reference tone.
Demonstration of audio principles to students.
Acoustics testing and equalisation.
Quality control and testing of sound cards.
White noise generator
Audio band signalling.
Hearing tests (under suitable medical supervision).
Features
Generate sine wave, square wave, triangular waveform, saw tooth waveform, impulse, white noise and pink noise.
Supports frequencies from 1Hz to 22kHz bandwidth (subject to sound card).
Multiple simultaneous tones (1 to 16 tones can be created at the same time) (useful to create harmonics).
Mono or separate stereo operation (ideal to create dual tones or 'beats').
Tone Sweeps (Log or Linear).

:::Borina Amaterska Svastara:::
but lm ic is hard to find
nch is good but my work bench and my pc is separated pc is in my room i want something that be fixed in my workbench
thanks any way

dc protect
dear apexaudio
greetings want to ask if on applying dc voltage to 150 k resistance will relay come on and led come on all other functions of dc protect
working only need to know if dc 15 volt from regulator fed to 150 k resistor will energise relay
thanking you

Hi,
are you asking if a 150k resistor in series with the 15Vdc supply can activate a relay drive circuit?
If that is the proposal then the 150k can pass a maximum of 100uA. Will the relay drive circuit trigger on a 100uA signal?
If instead your proposal is to feed a relay via the series 150k, then there is no way a relay can pull in with a 100uA supply.

Yes 15 volt from regulator fed to 150k will activate DC protection, relay come off and protect led come on.

Nice work, I suggest to put BD241C on heatsink, plastic case of outputs have lower temperature than metal. Do you have case for your H900?
Regards
thats real nice work and those heat-sinks & toroids just love them ............... how did u manage them in delhi .......
