Üks väga hea konspekt antenniteooriast. Põhirõhk amatöörvastuvõtul ja -saatmisel, aga huvitavat leiab ka tavaline satifänn.

Tänan Sind väga!

See on päris lahe infomaterjal,
mida saan enda õppetöös ilmselt kenasti ära kasutada.

Suur tänu!!!

teooria ja praktika.

minul on 3m -se mõõdud:

300cm , sügavus 46cm.

seega lnb kaugus peab olema 120cm (focal lenght) ja fD suhe on 0,4.
panen hiljem ühe lingi ka..

Satelliidi teekond Maa peal alates ehitamisest kuni ülessaatmiseni. Jutt inglise keeles, aga palju pilte ja videosid.

Walther Fisher "Digital Video and Audio Broadcasting Technology – A Practical Engineering Guide" Third edition.

Vaieldamatult kirss tordil... 828 lk lugemist.

"Digital Video and Audio Broadcasting Technology – A Practical Engineering Guide" deals with all the most important digital television, sound radio and multimedia standards such as MPEG, DVB, DVD, DAB, ATSC, T-DMB, DMB-T, DRM and ISDB-T. The book provides an in-depth look at these subjects in terms of practical experience. In addition it contains chapters on the basics of technologies such as analog television, digital modulation, COFDM or mathematical transformations between time and frequency domains. The attention in the respective field under discussion is focussed on aspects of measuring techniques and of measuring practice, in each case consolidating the knowledge imparted with numerous practical examples. This book is directed primarily at the specialist working in the field, on transmitters and transmission equipment, network planning, studio technology, playout centers and multiplex center technology and in the development departments for entertainment electronics or TV test engineering. Since the intire field of electrical communications technology is traversed in a wide arc, those who are students in this field are not excluded either. The third edition of this well established reference work includes the new formats MPEG-4 und IPTV, and it already gives an outlook to the newest standards like DVB-SH and DVB-T2.
