21. FM system produce an analog audio signal , meaning they have extremely high fidelity. 22. These items discussed thus far affect the level of audio signal . 23. Committee rooms are equipped to send and receive both video and audio signals . 24. The digital audio signal is available to approximately 53 % of Czech inhabitants. 25. Audio signals are alternating current and so are attenuated by inductance.26. To mask this, the encoder subtracts the synthesized sinusoids from the original audio signal . 27. Ideally, this ensures that an audio signal never exceeds the amplitude of the threshold. 28. The tuning eye was driven by the AGC voltage rather than the audio signal . 29. Temporal aliasing is a major concern in the sampling of video and audio signals . 30. Unlike contemporary sequencers that only generated voltages, the 1050 could also sequence audio signals .
