<p>The receiver has gates in the hf circuit, blocked when an interference detector recognises an interference pulse and delivers a blocking pulse. Output of a first gate (6) in the if circuit is connected to the input of a second gate (7), also in the if circuit, through a store (8) and an if selection unit (9). Interference detector (4) output is connected through a pulse shaping stage (5) to the inputs of gates (6, 7). Stage (5) is such that the duration of blocking pulses is equal to an integral multiple of the period of the if selection unit (9) resonant frequency.</p> |
