Filter banks are widely used in variety of applications such as signal compression, multi-channel transmission, conditioning of power supply, coding and decoding of signals, etc. Perfect reconstruction filter banks are used in the applications where it is essential to reconstruct the original signal with minimum errors. Compression of satellite vibration test data is one such application where perfect reconstruction filter banks can be used to design wavelets. These wavelets are used in transform coding stage of compression algorithm. It is required to have higher order for filters used in perfect reconstruction filter banks, to ensure better filter characteristics. The study carried out in this work, estimates the upper bound for order that can be assigned to filters used in perfect reconstruction filter banks.
