I suggest you record and FFT your power supply noise, then replace mic with a resistor then use a sine signal from a sig generator and compare results. 8 bit PWM will be quite poor for sound quality. It should be a sigma delta type.
Hello, I want to design a RF signal generator. Can you guys kindly let me know how to do so? please help:-D:-D
hi I have 40Khz 50wat ultrasonic transducer Can i operate these device at low power level (1 to 5 watts) by reducing applied voltage?
Hello, we are a cycle / recycling company in London (electronic amateurs with some help from students). we are a facing a problem with a sound system, we have previously powered with 12V leisure batteries. now we have got us a generator 2.2kW max power out put and we need to convert the 220V power output to 12V. The challenge is, that we need high
I remember seeing that the sine waveform from an old 8038 function generator IC had sharp triangle peaks. They caused the sinewave to look funny and make a low buzzing sound. But the distortion measured 0.5%. 0.001% distortion looks and sounds good.
Hello all, there are some micro-controllers with COG or complementary output generator to create a complementary PWM signals. I do understand how to create them and etc but do not know whats their use in real life applications and use of dead bands etc. I may sound like a newbie but after searching on google i could only find that these type of PW
As for your pulley/ belt/ gear ratio, the aim is to use the highest ratio that will still let your turbine spin the generator. The more current you try to draw from the generator, the harder it becomes to spin. As a result the turbine slows down. It will take some experimentation to find a gear ratio where you obtain maximum torque from your turb
You can certainly design a very sophisticated electronic system to deter skunks. But you have written that to deter a skunk, that sound of crinkling plastic works well, so- use this idea and make a generator of such sound! Maybe a tiny toy motor driving a cam with a Doritos bag would be the easiest way to go...
Hi All, I need to interface buzzer/ringer in my project to generate various sound (polyphonic, melodious rings) using MSP430G2452. If anybody have developed such application, please share the schematic & code (.c file). Thanks in advance. - Amit

Hello sir, I want to make circuit using single 555 timer ic so as to make a sound of simple beep beep beep beep.the circuit must have ability to vary the time period for the beep.i don't want to make sounds as it happens in buzzer or emergency door alarms.just simple light sound of beep beep it is possible with a single (...)
Hi guys, I need you guys expert advice. I'm new to vhdl language. My project is to make a musical score generator using VHDL. It will be implemented on a DE2 board,altera. The idea is, when a key/tone is played and the DE2 boards picks up the sound and generate the appropriate musical score. Can anyone help me out with this. Please. Thanks.
anyone know how to create a 1Hz pulse from 50Hz AC power supply? it is used for the CLK input of a digital clock thanks in advance

Hello, I would like a schematic of a simple sound recorder and player using microchips. It will be used to write and play short sound files. I have seen the isd2560 but I was wondering of a more readily available chip version exists. I have seen also this, EPROM AF generator by Harry Lythall which i
Did you configure the Baudrate generator for 1 MHz ?. This together with the 1 MHz fast I2C mode options is all you need to do. Keep in mind that the clock rate is 1 MHz so transmisson of 16 bits takes 18 us to complete !!..
A spectrum analysis is a plot of amplitude against frequency. What are you trying to measure? If the sound source can be a signal generator then you could sweep that. If the sound source is not generated by you then you could maybe use a tunable bandpass filter. The best way would be with a fixed filter, mixers and swept local oscillator (...)
I am working on a small circuit where an LED will activate a photodiode that controls a series of gun, blaster and explosion noises. I am thinking of the 8 sounds that were popular in cheap toy guns. Heres a youtube video of the sounds I am looking for: YouTube - Executor 8 sound Keychain The pr
I am trying to use an audio generator to produce frequencies (1 to 300 Hz), in order to use them as input to a microcontroller. I have taken the output of the sound card, and made a simple circuit with LM393 comparator to produce a 5v TTL pulse. But when I do this and check the output (with a logic analyzer, I don't have a scope) I see that there i
Hi. I have a PC program that generates a waveform on the sound card. I would like to use this to inject a square wave to a circuit. Problem is, I don't think I can connect it directly to the circuit as the output volume of the sound card is not enough for my signal conditioning circuits (3.3v zeners). I would like to take the output of the (...)
I don't understand what you are describing. Where does the graphic equaliser fit in? What you have described seems to be a tone generator. Keith.
I was my first thinking, a 51 core uC; but I got the answer. It is a sound generator ( it is a AY_3_8910 compatible ). Regards.
How can i use my laptop PC windows VISA computer to be like a oscilloscope? or Logic analyzer or spectrum analyzer? Where can i get free wavefiles that sweep frequencys? different wavefile duty cycles to adjust ? Free software function generator for computers? Instead of buying a pricey arbitrary function generator that has noise wavefil
hi everyone!!! can anyone help me in our research?? our project is a microcontroller based digital clock with alarm system... our problem is on alarm system... we want to generate an alarm from a sound generator and then to be followd by a recorded voice telling the time... we want to use midi voice in telling the time.... can anyone tell us how to
You can generate a signal directly from your PC using the sound card- I am not sure if that is what you want to do. Check this out: If you indeed want to set the waveform outside the PC you will of course need an external waveform generator. You either have to build one, in which case you
:?:dear readers, recently i had bought a SRM400 module.i would like to know, are there any ways to generate excitation signals/pulses to the SRM400 without the use of function/waveform generator? or am i dreaming? i am looking forward to your replies:D A.S.A.P thank you very much:D
External crystal must be used if one needs precise timing. Examples: - Baud rate genarator, if you use UART, - sound or other frequency generation - time interval measuremant and so on. The 1-2% of the claimed internal generator tolerance is too bad for such cases, especially if ambient temperature and/or power voltage can vary.

Dear all : Does anyone know how do to 60HZ zero cross sync generator ? Thanks
I found this site while looking for free electronic software, the have a very big selection listed under "free software" all 100% funtional, no time demos either. also software to turn your pc into test equipment using sound card as input. scope, function generator etc. great stuff.:D
Ultrasonic transducer works like a "microphone" for reception and as a "speaker" for transmission and in the latter case you have to drive it(transducer) with an ulltrasound wave in order to transmit it(wave) .. Some devices may have ultrasonic transducer and generator/driver built into one enclosure ..
Another program that can be used with a sound card is MiscEl. This program can be used as a function generator. To do this: Select menu "Calculations" topic "Waveforms" Select a waveform and fill something into the voltage fields (They are not used for the sound card output). Enter a frequence. Turn your volume control down :!: (...)

Andy, Klug is right, The simplest way is to build a spectrum inverter. You'll need a generator, above the audio spectrum, for example at FG=3.3kHz. This generator must be multiplied with your microphone AF ( FA=(0.3 to 3kHz), it can be done with the aid of a frequency mixer. As a result you will have two products : (FG+FA) and (FG-FA). The
