Quantizer
Quantizes a continuous input signal to discrete states.
Inputs/Outputs
input
Input signal.
This input accepts a double-precision, floating-point number or an array of double-precision, floating-point numbers.
quantization interval
Height of the quantization levels.
This input accepts a double-precision, floating-point number or an array of double-precision, floating-point numbers.
Default value: 1
type of quantization
Type of the quantizer.
This input accepts a ring or an array of rings.
| Mid-tread | 0 | Uses a mid-tread type quantizer. |
| Mid-riser | 1 | Uses a mid-riser type quantizer. |
| Round towards +Inf | 2 | Rounds the input elements to the nearest integer towards +Inf. |
| Round towards -Inf | 3 | Rounds the input elements to the nearest integer towards -Inf. |
| Round towards zero | 4 | Rounds the input elements to the nearest integer towards zero. |
| Round away from zero | 5 | Rounds the input elements to the nearest integer away from zero. |
Default value: Mid-tread
Algorithm Definition for the Mid-Tread Quantizer
The mid-tread quantizer uses the following equation to quantize the input signal.
where
- y is the output signal
- u is the input signal
- is the quantization interval
Algorithm Definition for the Mid-Riser Quantizer
The mid-riser quantizer uses the following equation to quantize the input signal.
where
- y is the output signal
- u is the input signal
- is the quantization interval
output
Output signal.
This output can return a double-precision, floating-point number or an array of double-precision, floating-point numbers.
