In this paper we propose a discrete-time FIR (Finite Impulse Response) filter which is applied as a square root Nyquist filter and fractional delay filter simultaneously. The filter enables to substitute for a cascade of square root Nyquist filter and fractional delay filter in one device/algorithm. The aim is to compensate for transmission delay in digital communication system. Performance of the filter as a matched filter is evaluated using a newly defined energetic ISI (Intersymbol Interference) measure and ability to eliminate the ISI involved by fractional delay of symbol shaping filter in the transmitter or by channel delay is shown. Considerations and main results of the contribution are documented by eye-diagrams and the SRRC filter responses.
