“…All-pass active RC-filters (ARCF), which provide amplitudefrequency responses (AFR) of low-pass filter (LPF), high-pass filter (HPF), band-pass filter (BPF), rejection filter (RF) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] at different outputs, are attractive for production in a form of special structural crystals [17,18] in conditions of small volume specific type of electronic equipment. At the same time, the application of promising electronic component base in ARCF, for example, differential difference amplifiers (DDAs) [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33], which provides new properties of frequency selection devices of this class, is of considerable interest.…”

We have suggested an architecture of the second-order all-pass active RC-filter (ARCF), based on three differential difference amplifiers (DDA's), which provides full set of amplitude-frequency responses (AFR's) (low pass filter (LPF), high pass filter (HPF), band pass filter (BPF), rejection filter (RF)). We have given the basic equations, which allow ARCF's. The results of computer simulation of the LPF, HPF, BPF and RF's are discussed. In case of small volume production it is possible to produce the given ARCF in a form of specialized structural arrays, in which LPF, HPF, BPF and RF characteristics are realized by using one of the seven inputs, to which the processed signal is supplied, and four outputs, from which the said signal is outputted. The ARCF is noted, because its transfer ratio and pole frequency are not changed, when the pole Q-factor is adjusted.
