bionet.ted.asdm.asdm_recoverable¶
- bionet.ted.asdm.asdm_recoverable(u, bw, b, d, k)¶
ASDM time encoding parameter check.
Determine whether a signal encoded with an Asynchronous Sigma-Delta Modulator using the specified parameters can be perfectly recovered.
Parameters: u: array_like of floats
Signal to test.
bw: float
Signal bandwidth (in rad/s).
b: float
Decoder bias.
d: float
Decoder threshold.
k: float
Decoder integration constant.
Returns: rec : bool
True if the specified signal is recoverable.
Raises: ValueError
When the signal cannot be perfectly recovered.
Notes
The bound assumed by this check is not as strict as that described in most of Prof. Lazar’s papers.
