A transimpedance amplifier is coupled to the low-pass filter and is adapted to receive the low-pass current signal, the transimpedance amplifier being adapted to generate an intermediate frequency voltage signal proportional with the low-pass current signal. A first switch is adapted to receive a signal proportional with the intermediate frequency voltage signal at a first end, a second end being coupled to the input terminal and a second switch is coupled between the input terminal and a reference terminal. The first and second switches are mutually exclusive in an ON state in a specific mode of operation of the multimode receiver.

    Abstract: Calibration data for calibrating time to digital conversion is obtained by switching a feed circuit (20) of a time to digital converter between a normal operating mode or a calibration mode. A delay circuit (22) with a delay circuit input and a plurality of taps outputs respective, differently delayed versions of a signal from a delay circuit input. A sampling register (24) has data inputs coupled to the taps, and samples data from the data inputs in response to an active transition at a clock input. When in the normal operating mode, the feed circuit (2) feeds an oscillator signal of an oscillator circuit (10) to the delay circuit input and a reference signal to the clock input of the sampling register (24). When in the calibration mode, the feed circuit (20) supplies signals with transitions having timing controlled by the oscillator signal to both the delay circuit input and the clock input. The feed circuit (20) provides for selection of transitions of the oscillator signal that control timing of a first active transition at the clock circuit after a transition at the delay circuit input. A control circuit (28) switches the feed circuit between the normal operating mode and the calibration mode, and controls the feed circuit (20) successively to select a plurality of different transitions to control timing of the first active transition in the calibration mode. The control circuit reads out resulting data from the sampling register (24) for each selection and determine calibration data for the oscillator signal from said data.

The results of experiment showed the showed that the prevention rate of the Fusarium wilt of banana reached more than 80% and the incidence rate can be controlled to less than 5% even on the seriously diseased terraces (seasonal incidence rate of 15% or more). The fertilizer can control the wilt effectively if they are applied to soil in successive years.

To compensate for phase errors the schematic topology of the first and the second waveform combiner circuit are arranged to be fully symmetrical to each other in that in the first waveform combiner, the circuit part for providing the function of the second waveform combiner is used as a dummy circuit, and in the second waveform combiner, a circuit part for providing the function of the first waveform combiner is used as a dummy circuit. Accordingly, the sources for providing the multiple phases of the digital local oscillator signal see the same load, and hence required phase shift is guaranteed.
