11. It is a 50 % duty-cycle signal that has the same frequency as the sample frequency . 12. Fig . 1 shows the waveform of a piano music audio file with 44100 Hz sampling frequency . 13. :Aliasing because the sample frequency of the television is close to the sample frequency of the monitor. 14. :Aliasing because the sample frequency of the television is close to the sample frequency of the monitor. 15. VMR-WB uses 16 kHz sampling frequency . 16. In practice, the sampling frequency is often significantly higher than twice that required by the signal's limited bandwidth. 17. AMR-WB uses 16 kHz sampling frequency with a resolution of 14 bits left justified in a 16-bit word. 18. Apple has then decided to create their own protocol, imposing all parameters related to synchronization like the sampling frequency . 19. In this case the incoming frequency is 100 Hz, so the sampling frequency must be at least 500 Hz. 20. The second is that a series of photographs may be taken at a high sampling frequency or frame rate.
