ABSTRACT:
The present invention provides a burst noise canceling apparatus which can remove burst noises even in a one-time data, without the need of a large amount of memory. The device according to the present invention incorporates an analog-to-digital converter for sampling a received MR signal to convert it to digital value to output it; a FIFO for delaying the digital value by delay time before output; a burst noise detection circuit for outputting a detection pulse upon detecting the presence of a burst noise in the received MR signal; a shift register having a first output which goes to “1” for the time corresponding to a pulse width of the detection pulse after elapsed time L−B since the detection pulse is read, and a second output which goes to “1” for the time corresponding to the pulse width of the detection pulse after elapsed time L+A since the detection pulse is read; an up-and-down counter which counts up at the rising edge of the first output and counts down at the falling edge of the second output; an OR circuit for outputting “1” when a count of the up-and-down counter is not “0” as a removal instruction signal; and a data removal processing unit which forces the output of the FIFO into “0” when the removal instruction signal is being output. The device is capable of removing the burst noise even in a one-time data, without the need of a large amount of memory.
