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 :!: (...)

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 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
I'm interested in designing binaural beat generator using microcontroller. Any sound chip suited for this task and available for online purchase ?
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 ..

i have a problem here for my final year year project. i was assigned to detect a sound origin in a closed room. i have to develop a device, which is able to detect the sound origin outside that closed room. the sound source (mono-tone) is from a normal sound generator, with a known frequency, may be is (...)
>>741 Opamp is not accurate enough for this operation. What do you mean by NOT ACCURATE ENOUGH? It has a GBW of around 1 MHz and that should be enough be Audio signals. >> I tried to use a non-inverting amplifier using 741 Opamp and a 9V battery to amplify and DC shift the signal, I designed the circuit and connected the output signal to an o

:?: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
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. 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 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
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
Now I want to use a fan for my frequency generator. I am fraid of adding noise by the fan. The following is a picture from one fan datasheet? What is the most important for considering the dc fan? The RPM or the sound pressure? Thank you very much.
Plates for the generator, frequency meter and noise generator were ordered before. A plate to the generator control and housing were projected then. Some buttons from old amplifiers served as a tool to change ranges

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
Hi you can use the CTC mode Of Avr Timers To generate a Continual 19KHz Square Wave then you can Control This Signal By an And Gate in Output of the microcontroller or you can control this signal by Enable or Disabling of Wave generator Output Enable Bit Good luck
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

I'm looking for an RF signal generator, 0.001 to 3GHz or there abouts. I've looked at a few different models, but the price tag is kinda high for a small (ok, tiny) company. I'm looking for reasonable performance at low cost. What do you use, and do you like it? Thanks

have anybody been involved in designing a PRBS generator above 500 Mbps for test and measurement equipment for optical communications? i want to design a 2.5 Gbps PRBS (2^7-1), but none experience in this field yet... any schematics, links or tips about this welcome! regards, rfmw
I need to create clk and clk bar from a single clk generator with frequency 27 MHz..i tried to use NAND latch but i i found an overlapping btw the clk bar and the clk..noting that i'll take the clk bar from the latch o/p and the other o/p will be high always(i think the i/p speed is very fast to the circuit so that it doesnt respond to it).
Lt-Rt gives surround but with dialogue leakage. We need some kind of variable gain control to eliminate dialogue leakage. Has anybody worked on this? Preferably I want suggestions using analog design. bimbla.
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
