"In paper here are discussed some possibilities of filter optimization by using of active buildings blocks (simulated inductors and frequency dependent negative resistances - FDNRs) with modern active elements at higher frequencies. In some practical examples there are briefly prescribed new possibilities and resulting parameters of designed and realized ARC low pass, high pass and band pass filter types with different modified approximation functions."@en .
