Evo ga još jedan...

Odakle počeše da stižu u naletima?

Nisam stein ali: „plivajući“ koje pominjete se odnosi na floating-point. A „Matissa“ bi trebalo da je mantissa... Malo pristupačne matematike...

Naprotiv, pa to je i suština/srž onoga što nas sve ovde povezuje. Da ne pominjem da je i uživanje nekako zarazno... Pravi sleeper. Pozdrav za obojicu.

Kako „oprati“ ime nedužnog Gundry-ja: Well, of course having found this, I have to jump in. My father, Dick Gundry, who spent almost all his working life in the BBC and was for many years responsible for maintaining technical standards in BBC Radio (which have sadly gone down since his retirement in about 1971), and who was known behind his back as golden ears, would not have been pleased to have his name attached to a deliberate departure from a flat frequency response in loudspeakers. Has anyone any idea on how this term arose? It must have been much more recent than 1971. One of my father's responsibilities back in the late 1950s and early 1960s was the development of stereo techniques in preparation for a means to broadcast it. (Some of those early experimental recordings have more recently been issued on CD by the BBC). At that time the BBC developed its own monitoring loudspeakers on the grounds that commercially available ones were generally not very good. I used to say that loudspeakers were either good or loud but not both! During early stereo experiments it became apparent that the best BBC monitoring speakers of the day did not perform well in pairs for stereo because they did not match each other closely enough, particularly in phase response, so central images tended to be diffuse. A major reason was that to accommodate variations in the drivers each and every cross-over network was adjusted for a flat amplitude response. A new range of speakers was developed, but it is possible that at least for those first ones, the uniformity was considered more important than perfect flatness, and thus the speakers may have shown the "Gundry dip". However it would not have been a design aim but a side-effect, and in any case my father would have had no input to the designs, which were developed at the BBC Research Department (Dudley Harwood, Spencer Hughes et al.) Kenneth Gundry, San Francisco I can confirm Rob Wansbeck's recollection of some TV studios, at BBC Television Centre at least where I was for two or three years in the mid-1960s, having available small loudspeakers representative of typical TV sets to permit a check that the programme remained intelligible when reproduced over poor audio equipment. However, I am quite sure that has nothing to do with the "Gundry dip"! I still would like to know how my father's name became associated with something that I am sure he would not have endorsed. Kenneth Gundry ...?

Nema tu undergound-a kako ga Ti posmatraš Valja imati na umu da je to, u suštini, sve dobra matematika ispod... TF je moćna i svestrana alatka ako se ume upotrebiti, pojačala su samo jedan mali primer.

Magla je magla odakle god da dolazi...

Nema ime, ne da ga ja (po)zna(je)m. Otac mu je VSAudio a.k.a. Savo... Visatonci su mu d(ij)elovi... Čak sam ih i ja prepozn'o... Pošto mi je, davno, mlađi potomak oteo Differo-e i, čak, odneo, sada, u EU, dugo sam čekao povratak nekih mališana. Da oni veći ne budu Peerless.. ;P Za PhotoFun je zaslužan uređaj Tebi (još bolje) poznat...

Neuko/naivno i dalje volim trafo na tom putu... I dalje ako neko ima pair 1:1 može mi ponuditi... Za trenutke kada TVC nije na putu...

Pa, naravno, tako je manje opterećenje... ((((((( ))))))

Gde „okolo naokolo“ kada je na istom mestu kao i tolike godine...? Da, sličica camera-e nije više baš „u oko“ ali je onaj glavni tamo gde je bio od kada se pojavio...

Pa, ne baš/uvek... Brojke su neumoljive. O SW da i ne pričam. Ako se u jednačinu unese i cena... Onda još manje...

Slabljenje je, kako i piše, izvedeno deljenjem sa 2 (pomeranjem za jedno mesto u levo, da pojednostavim bez gubljenja smisla)... Time se gubi, nakon izvesnog nivoa slabljenja, određeni sloj izvornih podataka. Naravno, to je izraženije kod manje učestanosti uzorkovanja nego kod veće. Obim tog gubitka lako postaje srazmeran pa i veći od jitter-a i sličnog... I dalje, gledano iz moje oblasti zanimanja/poznavanja, glasam za slabljenje na izlazu.

Ako neko bude kupovao i ostane mu viška rado bih (if the price is right) nekoliko iz viška otkupio.

Kao što i obećah, posle par sekundi (starci su sporiji od mladih) pretrage: http://www.diyaudio.rs/topic/1258-balansirani-razdvojni-transformator/?hl=balansirani To/ovo nije jedino m(j)esto gde s{mo,am} o tome pisa{li,o} ali...

Kad/ako budem imao vremena, potražiću...

365/24/7 već par+ godina, pisao sam o tome.
