摘要： An arrangement for the transmission of magnetic resonance signals that are received with the aid of local coils is provided. The magnetic resonance signal is fed to an analog/digital converter and digitized by the analog/digital converter. The magnetic resonance signal is compressed in amplitude before being fed to the analog/digital converter, is low-pass filtered or band-pass filtered, and is expanded after digitization by the analog/digital converter. A clock rate that is higher by a factor 2n than a sampling rate n of the analog/digital converter (ADC) is used for the digital expander. A digital equalizing filter for compensating for a filter transmission function in a transition range may also be used.

摘要： An arrangement to transmit magnetic resonance signals has at least two reception branches. Each reception branch contains a single antenna of a local coil as well as an amplifier connected with the single antenna, such that an amplified magnetic resonance signal is formed from a magnetic resonance signal that is acquired via the single antenna. In a multiplexer, each input is connected with a respective reception branch, such that the amplified magnetic resonance signals of the reception branch are combined by the multiplexer into a resulting signal using a time multiplexing method. A transmission path is connected on one side with an output of the multiplexer and on the other side with a receiver, such that the resulting signal is transmitted from the multiplexer to the receiver via the transmission path.

摘要： In a method and device for the transmission of a multiplicity of signals having different frequencies between a base station and a module situated at a location remote from the base station via a single, common cable connection, some of the signals being transmitted from the electronic assembly to the module and, in general simultaneously, the remaining signals are transmitted in the opposite direction. Each of the base station and the module has bandpass filter bank therein having a multiplicity of bandpass filters, the number thereof being a function of the number of channels to be transmitted, with which the respectively received signals are spectrally separated from one another so that they are available for further signal processing in the base station, or for further use in the module.

摘要： In a dynamics compressor, an analog signal to be compressed is supplied to a first amplifier stage as an input signal, and the output signal thereof is supplied to the next amplifier stage as an input signal, and so on for a number of successive amplifier stages. Each amplifier stage amplifies its input signal with a stage amplification until it reaches a stage limit level. The analog signal and the respective output signals of the amplifier stages are summed in a summation stage to form a sum signal. Above a minimal level, the magnitude of the curve of the sum signalroughly corresponds to an exponent characteristic of the magnitude of the analog signal.
