Analog & DSP Filters Options
Description
Frequency Devices’ ASC-50, is a laboratory bench-top
programmable instrument that combines familiar
analog signal input and output with the power and
flexibility of DSP. The ASC-50 provides the user with
finger-tip control of filter type, (low-pass, high-pass,
band-pass, and band-reject), operating frequency,
pole/bandwidth configuration, pre and post gain
settings, and analog/DSP filter functions - including
many not available through conventional analog
techniques. All are accessible at the touch of a button.
With a frequency range from 0.1Hz to 30kHz
combined with amplitude response of Butterworth,
Chebychev, elliptic and finite-impulse-response (FIR)
filter functions, the ASC-50 offers wide tuning flexibility
without the need for pre-defined programming.
An analog instrumentation interface provides input
gain; DC offset control and variable output gain along
with selectable single-ended and differential inputs to
accommodate a variety of driving signals. Additionally,
input DC-offset control is provided with expanded
resolution. With the exception of filter and frequency
changes all parameters of the ASC-50 can be altered
on the fly without halting signal flow. Real-time bypass
and gain-control facilitate test comparisons with and
without the filter activated.
A four button touch-pad coupled with a liquid-crystal
display (LCD) affords the user complete control of
various signal conditioning functions. Through the
LCD, the operator is prompted by a selection of
several filter types, functions, frequency and gain
settings. Less than optimum selections are indicated,
providing guidance without regimentation. Saturation
(over-range) conditions are indicated on both the input
and output permitting ease of system setup and use.
