Abstract
An exponential signal generator having a memory, a scale unit and an adder. A value stored in the memory is scaled and added to itself to produce a new value for storing in the memory. The exponential signal is represented by the exponential value.
Claims25
An exponential signal generator comprising:
- a first memory for storing a first exponential value;
- a scale unit coupled to the first memory to receive the first exponential value and produce a scaled value;
- and
- a first adder coupled to the first memory and the scale unit to add the first exponential value and the scaled value to produce a new first exponential value for storing in the first memory.
