Prof. Tzong-Lin WuEMC LaboratoryDepartment of Electrical EngineeringNational Taiwan University2011/2/21 Modulation Techniques1MW & RF Design / Prof. T. -L. Wu2011/2/21 Analog Modulation : AM, FM and PM. Modern wireless systems use digital Modulation . More spectrum efficient, less power required and error correction Better immunity to fading. Study the effect of noise of digital Modulation , the Modulation and & RF Design / Prof. T. -L. Wu2011/2 Analog modulation3MW & RF Design / Prof. T. -L. WuBecause the IF signal in a receiver contains noise from the antenna and receiver circuitry, as well as the desired signal, the characteristics of the demodulator play a critical role in the overall performance of the wireless modulation4MW & RF Design /
2011/2/21 MW & RF Design / Prof. T. -L. Wu 11 A more realistic result is found by expressing the input noise power in terms of the power spectral density of the white noise at the input to the IF stage.
