发明名称 SEQUENCY FILTERS BASED ON WALSH FUNCTIONS FOR SIGNALS WITH THREE SPACE VARIABLES
摘要 A sequency sampling filter based on Walsh Functions for signals having three space variables, x, y and z. Voltages derived from the space domain are transformed into voltages in a sequency domain. The filtering process is performed by not feeding certain voltages a (k,m,n) to a circuit which performs the inverse transformation of voltages in the sequency domain back into the space domain.
