Although there is no evidence of which type is dangerous I will like to put it this way:
I have felt the electric shock of a telephone line (40 V DC aprox) in my hands and also felt 120 volts AC in my tongue (don't ask why please, i was too young) and believe me I still remember those 40 V DC.
geometrical meaning of convolution
Convolution or multiplication are just two faces of the same coin.
If you multiply to signals in the time domain you are really convolving them in the frequency domain. The opposite is also true. This is known.
Now the physical meaning of this is that...
Hi,
Let me try to explain it the better I know.
First of all the letter used ( J ) is a letter to mean current density so this is why you see it in both types of currents.
Convenction Current Density is a relation of the current density to the speed of volumetric charge density in a certain...
Re: Increase sampling
Gaussian noise will not go out if you increase the number of samples or the resolution (8 to 16 or 24 bit) because it is mixed within the signal. Sampling the signal will sample the noise.
Increasing number of samples (oversampling) is used just to make sure you won't get...
+adc +sampling +clock +response +time
Sorry about that.
Lets go to you very first question and see if this time you get the answer you're waiting.
The sampling rate of and ADC is dictated mainly by the clock frequency. How to set it is explained in their respective datasheet.
Now, there are...
choosing a sample rate
Hello haydaa,
What Sal and Melc are trying to tell you is you have to know in advance which is your maximum signal frequency and then adjust your ADC clock to 2.1 times (raw calculation, depends on bandwidth) that frequency.
If you want to sample an 8 khz signal you can...
riaa equalization software audacity
I will recomend you Audacity Sound editor. It is a free audio editor with a RIAA equalization effect. I was having the same problem you have and using this software resolve my problem.
One note though, make sure you can deliver enough amplification to your...
