N is the sum of noise which is added from 0Hz to So I chose 74AC First floor is the part of digital and second is the one of analog.


I’m happy it looks so nice regarding flush. I planned to set chip capacitors which had about 0. Frequency response is a responce of sin wave. Luckily it easily sounded, but its sound was noisy and distorted. I guessed that I would probably want to convert something after completion.

I regret I’ve not use a flash. Marvelous sound were flown out from a tiny plastic speaker. 74hhc74ap is a photo datashset DAC has beeing sounded with optical input. I want sounds as true as possible. I often find DAC kits that adopt 2, 4 or 8 inparallel when I’m roaming the net. Avoiding incoming noises from unused digital input, I used relay and would hook up with one-side of digital input to DAI.

You shud use speaker unit as light as possible. If you use negative feedback, the induced voltage of speaker unit which willl be caused by acoustic pressure from outside will come in datasheet line-out and amplifier will compensate including this voltage, so we will be unable to sound true daasheet.

Speaker is bass reflex type and its unit is 12cm. He said following things eagerly in his lecture. Unit sounds based on this enclosure, so if this standard point moves, unit cannot reproduce true sound. Light unit as a feather can do.

This catch phrase is “realizing ritch bass and well spread mediant and treble”. It is not good to adopt negative feedback when you want true source sound. I was about to eat them by mistake. If you want a true responce of sound, you should design based on impulse responce. Please do at your own risk. Further more, it was already converted into DIP package. It may be good to adopt para-using film capacitors in couppling.

I want to try parallel use.

Then it got very clear and beautiful. TA is D-class amplifier and it uses PWM, so it would not good to include the noise which frequency is as high as switching one. So I took a action to remove.

If you can reproduce the original sound, you will be able to get enough bass edge. It is far from 74hc7ap thought of reproducing the original sound in the first place. A lot of recent audio DACs adopt the method of Delta-Sigma converter, so it will have many benefits actually. I liked this because it added beautifulness to the sound.

In my case, power amplifier had its own LPF. If we sample by over 2f, we will be able to restore avoiding distorted by LPF because fc gets to be much higher than 2f. I believed that it was a nice one. So I came to the conclusion that contemporary audio engineering had to be wrong. For larger image, please click.

I used blue LED as a indication lump. If you have a question or comment, please use BBS. This is excellent for the theme, “I want to make cool audio devices at small cost”.

My emplanation may be very doutful, so please refer following sites. Its bass might be cut off, so I added 2.
