<p>A delayed action circuit including input connections, a voltage - limiting circuit connected to the input connections, a resistance - capacitance integrating network connected to the voltage-limiting circuit and a threshold circuit connected to the integrating network, characterised in that the threshold circuit has a control input connected to the input connections for controlling its threshold voltage in response to the peak voltage of any signal applied to the input connections and thereby providing a longer delay in response to a higher peak input voltage.</p> |
