Patent ID: 8150325

Claim:
A signal processing system comprising: a signal processor having a plurality of circuits, each circuit being adapted to generate a blanking pulse signal having a given duration a predetermined amount of time after receiving a pre-trigger signal at a first input of the last mentioned circuit from one of a plurality of EMS transmitters and each of said plurality of EMS transmitters transmits an EMS signal at the end of its predetermined amount of time; a first signal router adapted to route pre-trigger signals from an EMS transmitter to at least one of said signal processor circuits; a second signal router adapted to route blanking pulse signals generated by and at the output of ones of said signal processor circuits to selected ones of a plurality of EMS receivers to protect them from signal interference caused by interference reflections of said EMS signals that are received at said receivers by either rendering said EMS receivers incapable of receiving any EMS signals during the duration of each blanking pulse signal or by rendering said EMS receivers incapable of displaying any EMS signals during the duration of each blanking pulse signal; and memory storing both the predetermined amount of time following a pre-trigger signal associated with each EMS transmitter and the duration of a blanking pulse signal to be routed to each EMS receiver, each predetermined amount of time and duration of a blanking pulse signal being retrieved from said memory following receipt of a pre-trigger signal and used to generate a blanking pulse signal.
