A detection device for detecting a blood count parameter of a blood component in a blood vessel comprising a transmitter, a receiver, a loss detector, and a processor. The transmitter injects a first transmit signal into the blood vessel at a first frequency and a second transmit signal into the blood vessel at a second frequency. The receiver receives a first receive signal at the first frequency and a second receive signal at the second frequency. The loss detector determines a first loss value on the basis of the first transmit signal and the first receive signal, and determines a second loss value on the basis of the second transmit signal and the second receive signal.

There is provided a method of determining a transmission quality when receiving audio signals which are transmitted over a frequency-modulated path in analog form. For that purpose a frequency-modulated audio signal is received and IQ demodulation of the input signal is implemented. The I- and the Q-path of the demodulated baseband signal are subjected to analog/digital conversion. Alternatively the input signal can first be digitized and then subjected to IQ demodulation. A multiplicity of N samples is detected. The amount of the N samples is formed. A reference value is determined from the amount of the N samples. Each of the N samples is standardized to the reference value. A measurement in respect of the fluctuations in the standardized amounts is determined. The measurement in respect of the fluctuations indicates the quality of the transmission path.

Disclosed is a base station comprising an antenna and a plurality of integrated transceiver modules. Each integrated transceiver module includes a radio and a decentral duplexer connected to the radio and the antenna for transmission of and reception of communication signals. The integrated transceiver module therefore modularizes the base station so that all of the components of a base station can be located on a single module (e.g., one printed circuit board (PCB)). The base station can be upgraded by inserting additional integrated transceiver modules into the base station.

The present invention provides a filter unit cell. The filter unit cell includes a variable capacitor coupled in series between first and second nodes and an inductor coupled in series between the second node and a third node.

Tunable radio frequency filter

The present invention provides a method and an apparatus for controlling a Q-factor for a filter. The method comprises stabilizing an active feedback to provide a variable feedback in a filter, varying the active feedback based on an input signal to the filter, and producing a desired Q-factor for the filter at a first frequency band, in response to the variable feedback. The method further comprises reconfiguring a center frequency and a bandwidth of the filter based on a channel bandwidth of the input signal to the filter to adjust the Q-factor for the filter in response to a second frequency band different than the first frequency band. By reconfiguring a center frequency and a bandwidth of a filter, the Q-factor for the filter, such as a flexible or reconfigurable filter, may be controlled across a multiplicity of frequency band signals. Using software, for example, a common signal path may be provided for the multiplicity of frequency band signals within a frequency agile radio of a base station by tuning the radio based on a variable feedback through realization of a negative parallel resistance. Thus, tuneability of the Q-factor may provide frequency agile radios that include flexible or reconfigurable filters in a base station to serve different frequency bands without changing hardware. In this way, significant savings associated with frequency agility may be obtained.
