Jawaabaha iyo sharraxaadaha waxay soo baxayaan markaad qaadanayso kediska.

  1. Waa maxay tilmaanta jireed ee dhalaalku ka faa'iidaysto?
    • Kala duwanaanshaha wakhtiga/wajiga ee imaatinka makarafoono badan
    • Midabka isha codka
    • Heerka batteriga ee qalabka
    • Heerkulka qolka
  2. Waa maxay farsamada ugu fudud ee loo yaqaan 'beamforming'?
    • Laablaabidda afraad
    • Dib-u-dhac-iyo-guud
    • Gating Spectral
    • Raadraaca gabbaadka
  3. What is the defining constraint in an MVDR beamformer?
    • Maximize every incoming direction equally
    • Remove the desired source before summation
    • Preserve the desired target response while minimizing output power
    • Convert the microphone signals into text
  4. Sidee beamforming la xidhiidha xakamaynta sanqadha- makarafoon?
    • Waxay si buuxda u beddeshaa oo ka dhigtaa mid duugoobay
    • Waa isku mid
    • Waxa kaliya oo ay shaqeysaa iyada oo aan wax habayn kale ah lahayn
    • Waxay kabaysaa iyadoo ku daraysa macluumaadka meel bannaan oo hal makarafoon ka maqan yahay
  5. Why can microphone spacing that is too large create spatial aliasing?
    • Different directions can produce indistinguishable sampled phase differences at a frequency
    • The microphones stop recording sound
    • The sample rate automatically drops to zero
    • The array loses all time information
  6. Waa maxay 'neural beamforming'?
    • Beamforming ayaa gabi ahaanba gacanta lagu sameeyay
    • Isku dhafka shabakadaha qoto dheer (tusaale, maaskaro ama qiyaasta jihada) iyo alwaax-sameeyaha
    • Meesha laga saaray dhammaan makarafoonnada
    • Nooc ka mid ah hal-channel garoon beddelka
  7. What can happen when an MVDR beamformer’s assumed steering vector is inaccurate?
    • The array automatically gains microphones
    • The audio changes into a spectrogram image
    • Its target preservation or interference suppression can degrade
    • The desired source is always amplified without limit
  8. What information determines the steering delays for a chosen look direction?
    • Audio file format and transcript length
    • Speaker age and language
    • The number of model parameters alone
    • Target direction, microphone geometry, and speed of sound
