where are you from?
Sir.....
Oh, ok
tell me about your main project!
Sir it was basically a development of our mini... after we developed the mini, we felt we could do it a bit further...3~30 cm range , dimensions 25x25 cm.. 3d user interface,bunch of rangers, for virtual reality, ease of use , simplicity, reliablity, blah..............
ok, ok good . Tell me about your mini then!
Sir a simpler version of the one i told you about, 10~80 cm range, one dimension,series of detectors simple , easy to use , flexible , addable as OEM, future of the interface ...more blah...
hmmm , your seminar, what was it about?
Sir digital audio systems sir..
Okay, tell me about noise reduction
OH?(feeling in my element ) 2 ways , equalization, companding , dolby a , b, c ,hx pro, magnetization+ tape transer magnetization curve,b in audio tapes, 120uS eq in tapes ,DBX , dynamic noise redn,compression, AGC, transmit, recieve, inverse characteristic, better noise performance
hmm... how about dolby, digital theatre systems ...DTS right?
Yes sir , in addition there is SDDS (sony) and THX(lucsfilm)
All of em are multi channel sound formats , typically 5.1.. lossy compression codecs, use redundancy in multi channel sound, dts-1.5mbps ,DD 448 kbps , dts on cd , dd on film only sync pulses for dts films..
what are the sampling rates in studios
44.1Khz, or usually oversampled, now dvd's take 48 or 96 or even 192... depends . Old story about how 44.1 was chosen becos VHS tapes were used and sony wanted some 74 minute orchestra to fit ..
hmm... digital radio?
hm... Digital broadcasting in AM band , low bitrates, SBR , better frequency range, am not used a lot(floundered a bit here , thankfully, he asked me about )
Software radio?
Well, normal radios-> baseband tuners , IF tuners , am demodulators, FM demodulators, diff circuitry, hardware , need to switch, costs , bulk etc
s/w radios -> RF-> DSP doing RF work, to give baseband signal, one rx can recieve entire band independent of modulation technique, ex my tv tuner can get TV and FM cos its the same freq band , diff modulation techniques , same hardware, only change of s/w ...
um... thats about enough...you may go now .. ask the next student to wait for a few minutes...(phew!)
