6.12: Signal-to-Noise Ratio of an Amplitude-Modulated Signal

WebNoise due to multiple earths can be avoided by good earthing practices. In particular, this means keeping earths for signal wires and earths for high-current equipment entirely separate. The recommended practice is to install four completely isolated earth circuits as follows: Power earth: Provides a path for fault currents due to power faults. WebAs we have seen, noise is an ever present part of all systems. Any receiver must contend with noise. In analog systems, noise deteriorates the quality of the received signal, e.g. the appearance of “snow” on the TV screen, or “static” sounds during an audio transmission. In digital communication systems, noise degrades the

WebUnder conditions of very low signal-to-noise ratio AM is the superior system. The precise value of signal-to-noise ratio at which this becomes apparent depends on the value of the FM modulation index. FM becomes superior to AM at the signal-to-noise ratio level used in the example (voltage ratio = 4, power ratio = 16 = 12 dB) at the Web16 de out. de 2024 · ADC quantization +thermal noise.
