Description
Design engineers now have an off-the-shelf
precision, dual channel hardware solution for
development of digital FIR filters that can be used
in production subassemblies.
generate FIR filter characteristics in a MatLab
V5.3 or V6.0 environment and directly load
standard or custom coefficient sets into the
SPPDM-01 platform via an RS232 interface
located
subassembly or from the SPPDB-01 development
board.
By utilizing the SPPDF-01 hardware with the
enclosed MatLab GUI, generated coefficients are
loaded directly into the removable SPPDM-01
platform
products.
product development and manufacturing cycle
times while providing precise unit-to-unit product
matching in a small 2” x 2” footprint that can be
reconfigured or upgraded in the field
SPPDM-01 FIR filter platforms operates over a
100 Hz to 20 kHz audio frequency range. Each
channel can be configured to provide up to 9-bits
of filter frequency programmability per channel.
This dual channel DSP design solution contains
anti-alias and reconstruction filters along with
ADC’s and DAC’s offering low noise and distortion
signal processing with THD approaching –100 dB.
Sampling at 48 kHz the fixed point DSP utilizes
32-bit math to achieve 24-bits of precision.
