Abstract :
For the original article see ibid., vol.28, no.11, p.1058-9 (1992). In the afore-mentioned paper Danyuk and Pilko proposed two practical configurations of the basic feedforward bridge amplifier. However, the commenters point out that the practical circuit which was illustrated in the authors´ paper does not work as indicated. They explain why this is so and propose a modification to the original circuit.
