Implementation of High Time Delay Accuracy of Ultrasonic Phased Array Based on Interpolation CIC Filter

In order to improve the accuracy of ultrasonic phased array focusing time delay, analyzing the original interpolation Cascade-Integrator-Comb (CIC) filter, an 8× interpolation CIC filter parallel algorithm was proposed, so that interpolation and multichannel decomposition can simultaneously process....
