Filter Design Toolbox

ProductFormat

The ProductFormat property values specify how the results of multiplication are quantized during the filtering operation. You specify these values with a quantizer. You set them according to the property values of a quantizer's:

• Format (except when the Mode property value is set to 'double' or 'single')
• Mode
• OverflowMode
• RoundMode

Default value: quantizer('fixed','floor','saturate',[32,30])

QuantizedCoefficients

The values for this read-only property are stored in a cell array containing the quantized filter coefficients calculated from the value of the ReferenceCoefficients property. The quantization is specified by the value of the CoefficientFormat property.

Default value: {1 1}

Remarks: If any filter coefficient overflows occur as a result of quantization, a warning is displayed.

The cell array for the QuantizedCoefficients property value has the same form as that of the corresponding ReferenceCoefficients property value, described in Assigning Reference Filter Coefficients.
