FIR filters have a great deal of interest in both analog and digital industries. In digital signal processing, these filters are especially important because they are used for signal separation and restoration. This paper aims to develop an efficient FIR filter with reduced area, delay, and power hence improving total performance. This method divides the input into its component residues using a residue number system and then utilizes a thermometer code to encode each residue. RNS, which provides rapid and energy-efficient computational systems, can successfully replace positional number systems. The primary RNS attribute that helps contemporary embedded systems is its energy efficiency. The most significant and frequently used operation on RNS components, including channel arithmetic units and forward and reverse converters, is modular addition. The adoption of thermometer coding is practical due to the small and medium dynamic range needs of low-power embedded and edge devices, which lowers power consumption and increases the energy efficiency of modulo arithmetic. The proposed work presents an effective FIR filter using a thermometer coding based on these methods.
