Measuring circuit for integrating electrical signals in a gamma camera |
摘要 |
A measuring circuit for integrating electrical signals. The measuring circuit comprises a delay line which is connected between the output of an integration stage and the input of a discharge stage in order to render the value of the discharge current dependent on a voltage which remains during said discharging. The circuit may also comprise a timing circuit which ensures that said constant voltage is maintained for a sufficiently long period of time. The measuring circuit may also comprise a circuit for advancing the opening a discharge switch in order to take into account the time required for transmitting the control signals for opening the discharge switch to this switch.
