Abstract:
A circuit arrangement for deriving the signal indicating noise in a received stereo multiplex signal, wherein the stereo multiplex signal is present as a digital signal with a first sampling rate that is substantially higher than twice the upper limit of the useful frequency range of the stereo multiplex signal, and the received stereo multiplex signal is passed through a low-pass filter. The low-pass filtered signal and the received stereo multiplex signal are subjected to decimation to a second sampling rate, which is higher than twice the upper limit of the useful frequency range of the stereo multiplex signal. The two stereo multiplex signals with the second sampling rate are subtracted from one another.
Abstract:
In a radio receiver with digital signal processing, a stereo multiplex signal received and the useful signals derived therefrom are processed in digital form at a first sampling rate. The subsidiary signals derived from the stereo multiplex signal are at least partly processed at a second sampling rate that is smaller than the first sampling rate. The sampling rate of the processed subsidiary signals are reduced to the first sampling rate with the processed subsidiary signals, acting as control signals with the first sampling rate, affecting the stereo multiplex signal and the useful signals.
Abstract:
A digital circuit arrangement for transforming an input digital picture signal onto a reference horizontal synchronizing signal raster derived from the system clock, which input digital picture signal is present at a system clock rate not locked with the input digital picture signal, which includes a correction memory (1), an interpolator/decimator (2), and a control member for the purpose of a transformation which is as insensitive to interference as possible. The control member receives a control deviation signal (d) obtained with the aid of a discriminator (4) by comparing a horizontal synchronizing signal in the input digital picture signal with the reference horizontal synchronizing signal, and the control member applies a first correcting variable (i) to the correction memory (1), the first correcting variable (i) indicating transformation of the input digital picture signal by integral multiples of the system clock period to be performed by the correction memory (1), and the control member also applies a second correcting variable (.alpha..sub.s) to the interpolator/decimator (2), the second correcting variable (.alpha..sub.s) indicating the transformation by fractions of the system clock period to be performed by the interpolator/decimator (2).
Abstract:
In a digital circuit arrangement for processing an analog video signal, which operates at a fixed system clock not coupled to the video signal, in which the video signal is sampled and which comprises a correction memory (4) and an interpolator with decimator (14) which are used for converting the digital video signal to a synchronizing signal raster predetermined by the system clock, there is provided that the correction memory (4) has a predetermined number of memory sections (5, 6, 7, 8) arranged for storing each the sample values of one picture line which sample values are written or read out at the system clock, that each horizontal synchronizing pulse of the still unconverted video signal triggers a writing process of the subsequent picture line into a memory section (5, 6, 7, 8) and that each horizontal synchronizing pulse derived from the system clock triggers a reading process of the picture line that follows the previously read picture line.
