(1) The research of digital pre-emphasis gradient waveform generator.

(2) TV pre-emphasis network in satellite communication is analysed, the circuit elements are determined according to the CCIR recommendation.

(3) Pre-emphasis filter is used, it aims keeping speech information best rather than eliminating the noise completely.

(4) Continuously variable controls allow precise restitution of any pre-emphasis curve ever used.

(5) A phase pre-emphasis technique used in an all-optical sampling orthogonal frequency division multiplexing (AOS-OFDM) system is proposed and demonstrated.

(6) Phase pre-emphasis is theoretically studied and introduced to reduce peak-to-average power ratio (PAPR) in optical orthogonal frequency division multiplexing (OFDM) systems.

(7) A method of eddy current compensation based on pre-emphasis of gradient current is presented in this thesis.

(8) Networks, device for pre-emphasis of higher frequencies. Right-click for de-emphasis of higher freq. , compressor, or expander.

(9) Pitch pre-emphasis technology was used to enhance the pitch search.

(10) These variables are carrier frequency off-set value, pre-emphasis factor, weighting factor, video spectral distribution and nominal peak to peak frequency deviation.

(11) A lot of useful information in the image locates at its edge, i. e. high frequency content in its frequency spectrum, so pre-emphasis system can be used to enhance the image.

(12) This thesis gives a detailed discussion about the gradient waveform generator (GWG) design with the analog pre-emphasis in the digital spectrometer system.

(13) To enhance the performance of the filter in the digital system, the pre-emphasis filter in a digital frequency-modulating exciter which is based on FPGA is designed and realized.
