ABSTRACT:
A signal-processing system, particularly adapted to digitally process analog signals, and including computation apparatus which carries out operations on the signals, also includes a control memory with storage locations addressable in predetermined sequences and an operand memory with storage locations addressable in variable sequences. The control memory contains control information which controls the operations of the computation apparatus and the operand memory contains operand information which is operated upon by the computation apparatus with the signals which are processed. The variable sequences in which the storage locations in the operand memory are addressed are in part determined by information in the control memory. The computation apparatus includes a multiplier, an adder, and a delay memory which is used in providing variable delays in signals during processing. The system is particularly adapted to provide digital reverberation effects, such as echo effects and the simulation of rooms (echo chambers) with variable characteristics. The system incorporates analog to digital and digital to analog conversion systems having ranging capabilities. Digital shifting structure with the capability to shift digits in adjoining digit positions to other positions representative of multiplication or division by variable factors are incorporated into the conversion systems. This eliminates the need to treat independent ranging digits during the computation process by providing an accurate, integrated numerical representation of the signals received and provided by the computation apparatus. Particular embodiments of the conversion systems and of the remainder of the signal-processing system operate in the desirable 2's complement (binary) number system.
