A pulse rebalanced servomechanism for converting a variable input EI into a digital output signal EO has integrator means (2), a feedback loop (5) applying a first train of pulses representative of the output of the integrator means to the input of the integrator means, whereby the integrator means is responsive to the difference between the variable input and the first train of pulses, and interpolating means (9) for producing a second train of pulses corresponding to the output of the integrator means (2), the pulse duration of the second train of pulses being less than the pulse duration of the first train of pulses so that the second train of pulses provides a finer resolution of the input than the first train of pulses, and combining means (15) for combining the first train of pulses with the second train of pulses to produce said digital output signal corresponding to the variable input. <IMAGE>
