Different possible realizations of the FTFN are evaluated. Its wide range of applications is investigated. The versatility and the flexibility of the FTFN is demonstrated and exemplified. Universal filters and sinusoidal oscillators based on the FTFN are designed. The advantages and the disadvantages of each circuit are indicated. The proposed filters are compared with new CCII+, Op Amp-OTA, CFA counterparts and the proposed oscillator circuits are compared with the previously published circuits. Experimental and simulation results confirming the theoretical designs are included.enThesis
