Error message :
Please enter a value less than half the sampling rate
All frequency values are normalized using the sampling frequency. Thus, the acceptable values for all frequency bands should be les than half the sampling frequency.
Error message :
Please enter a value greater than zero
Certain fields cannot have negative values or zero and need to have a value greater than zero in order to generate meaningful data.
Error message :
Please enter an even number of filter length
For the specific case of filters chosen, the program will check for the correct filter length required (ie either odd or even filter length).
Error message :
Please enter an
odd number of filter length
For the specific case of filters chosen, the program will check for the correct filter length required (ie either odd or even filter length).
Error message :
Overlapping band
edge frequencies error. Please ensure Band n upper band edge frequency is greater than Band
(n+1) lower band edge frequency
The program requires the subsequent lower band edge frequency to be always greater than the preceding upper band edge.
Error message :
Band n frequency range error. Please ensure upper
band edge frequency is greater than lower band edge frequency
For the same band, it is always required for the upper band edge to have a higher frequency value than the lower band edge.
Error message :
Singular matrix encountered! - Filter cannot be designed!
This message is displayed if the program encountered a singular matrix (matrix rank < matrix rows) in performing matrix inversion for the equiripple design.
Error message :
Transition width out of range. Please enter a value between 1 and
1/2 Sampling
Frequency
This message will be shown if the user has entered a transition width that is out of the range of 1 and half sampling frequency.
Error message :
Peak ripple ratio cannot be reach after 40 iterations
For the equiripple design, if the peak error ripple ratio cannot be achieved after a maximum of 40 iterations of the algorithm, this error message is shown.
Error message :
Please enter a value less than 16 for Beta
This error message is dedicated for the beta value field whereby we capped the beta value to 15.
Error message :
Please enter a positive number
Certain fields cannot have negative values, thus a positive value is required.
Error message :
Please enter a number greater than 2
This field is attributed to the filter length field whereby, the minimum required filter length that the program is going to process should be greater than 2.
Error message :
Error opening file
The program has encountered problems while attempting to load a previously saved file.
Error message :
Error creating output file
The program has detected a problem in generating the filter coefficients text file.
