The Hilbert filter shown in the drawing comprises four identical cells in the form of operational amplifiers OP1 to OP4 associated with resistors R1 to R4 and R and capacitors C1 to C4. Each cell has one of the output terminals 2 to 5. In such a structure, all the components, but the capacitors, can be easily integrated.
