  Using simulations and analytical approaches, we have studied single hit
resolutions obtained with a binary readout, which is often proposed for high
granularity detectors to reduce the generated data volume. Our simulations
considering several parameters (e.g. strip pitch) show that the detector
geometry and an electronics parameter of the binary readout chips could be
optimized for binary readout to offer an equivalent spatial resolution to the
one with an analogue readout. To understand the behavior as a function of
simulation parameters, we developed analytical models that reproduce simulation
results with a few parameters. The models can be used to optimize detector
designs and operation conditions with regard to the spatial resolution.
