11. Many embedded systems need to read sensors that produce analog signals . 12. On the receiving end the analog signal is converted back to digital data. 13. The channel 2 analog signal traveled a very long distance under normal conditions. 14. Analog signal processing is still important in the design of many control systems.15. WSVN ended programming on its analog signal , on UHF band following the transition. 16. This makes FETs suitable for switching analog signals between paths ( multiplexing ). 17. No such interference was noted with cellular telephones that use conventional analog signals . 18. Due to their analog signals only reach the immediate areas surrounding their transmitters. 19. The digital processing of analog signals in an HD radio delays them also. 20. In 1978, Intel released the 2920 as an " analog signal processor ".
