504 MUSICAL ApPLICATIONS OF MICROPROCESSORS INPUT S Fig. 14-16. Basic structure of transversal filter input sample times the first impulse response sample plus the (/- l)th input sample times the second impulse sample plus the (/- 2)th input sample times the third impulse sample, etc. for the entire set of impulse samples. Thus, every sample processed through the filter requires N multiplies and adds, where N is the number of impulse samples kept. Figure 14-16 shows a conceptual structure of the filter that is very easy to program. Essentially, the input samples are entered into a shift register with a tap at every stage. The output at each tap is multiplied by the assClciated impulse response sample and the product is summed with other products to produce the output sample. When a new input sample is entered, all of the old ones are shifted one position right and the sum of products is evaluated again. This is often called a transversal filter because each signal sample traverses the tabulated impulse response. Because of its simple, highly repetitive structure, such a filter lends itself well to hardware implementation. In fact, specialized Ies using charge-coupled circuitry have been built to implement filter functions useful in the telephone industry. 2000 REM SUBROUTINE TO IMPLEMENT A TRANSVERSAL FILTER 2001 REM INPUT SAMPLE IS Sl, OUTPUT SAMPLE IS S2 2002 REM IMPULSE RESPONSE OF FILTER IN IN ARRAY R, FIRST ELEMENT IN 2003 REM R(O), SECOND IN R(l),. ,., 2004 REM N IS NUMBER OF IMPULSE RESPONSE SAMPLES 2005 REM ARRAY S HOLDS PREVIOUS SIGNAL SAMPLES, MUST BE ALL ZEROES 2006 REM WHEN THIS ROUTINE IS FIRST USED 2007 REM P IS POINTER FOR S ARRAY, IT TOO MUST BE INITIALLY ZERO 2100 S2=0 2110 S(P)=Sl 2120 J=P 2130 FOR 1=0 TO N-1 2140 S2=S2+R(I)*S(J) 2150 J=J-1 2160 IF J
