Unformatted text preview: Radio and Television Lesson 1 1) Facsmile technology and fidelity-Slide 4 and 5-Fascimile-making a copy of something a. Fidelity- how much the copy resembles reality 2) What is transduction? Slide 8 and 9- definition- going from one form of energy to another-and know examples 3) Signal to noise ratio Slide 6- signal is clarity, noise is disruption, want to have high signal to noise ratio 4) Oscillation and the waveform- Slide 15- oscillation- the form of the wave, the vibrations 5) What are the five steps in signal processing? Signal generation, amplification and processing, transmission, reception, storage and retrieval (know order) 6) What are the three characterisitics of electromagnetic energy? Slide 13- radiant, constant velocity, wavelike motion 7) Velocity of electromagnetic energy- Slide 13- 186,000 per second 8) What is a cycle of a radio wave? Slide 22 9) What is frequency, what is frequency response? Slide 20-21- frequency- number of waves that passes a given point in a given time, response, how well a radio wave reproduces a range of audio frequencies 10) What does Hertz measure? Slide 24 11)What is pulse code modulation?- sampling the wave at various points, taking something that exists in reality and making a digital representation of that wave 12)What are the differences between amplitude and frequency modulation? Slide 19-20 13)Why is FM superior to AM in sound quality? Lesson 3- slide 12- better sound quality with FM, AM is more subject to atmospheric disruption 14) What is the function of a switcher? Lesson 2- slide 29- mixing video signals, mixing of different shots 15)Disregard 16) What is the difference between linear and non-linear editing? Lesson 2-slide 20- know definitions a. Non linear-digital editions, use computer to edit, software b. Linear-analog-the way it used to be, cut a splice film 17) What is the electromagnetic spectrum? Lesson 3- slide 1-4 18)What are the different behaviors of frequencies (ground waves, sky waves, and direct waves)? Lesson 3- slide 6-11 19)What is the carrier wave? Lesson 3-slide 2-the signal produced by a stations transmitter 20)What is the difference between VHF and UHF? Lesson 3 21) What is channel capacity? Lesson 3-slide 19-20 22)What is the bandwith for AM? FM? TV? Lesson 3-slide 20 AM- 10 KH, FM 200 KH, TV 6 MH 23)What are the differences between co-channel and adjacent channel interference? Lesson 6-slide 22 co-channel, within one market, having two channels 24)What are the two main solutions for overcoming interference? Lesson 6-slide 23-24 25)What is difference between analog and digital signals? Analog is a complete reproduction of signal (electric impulse-changes in power of frequency. The problems associated with analog are interference, loss of quality in frequency....
