In　this　article,　a　global　output　feedback　control　scheme　is　developed　for　a　class　of　uncertain　nonlinear　systems　subject　to　input　quantization　and　unknown　output　function.　By　employing　a　time-varying　gain　and　a　time-invariant　gain,　we　address　the　challenges　posed　by　quantization　errors　and　nonlinear　functions　with　an　unknown　linear　growth　rate.　Additionally,　we　determine　an　allowable　measurement　sensitivity　error　by　solving　a　straightforward　inequality.　We　demonstrate　that　the　proposed　scheme　ensures　global　asymptotic　stability　for　the　system　and　guarantees　that　all　signals　of　the　closed-loop　system　remain　bounded.　Finally,　we　validate　the　proposed　approach　through　a　mathematical　example　and　an　experiment　conducted　on　the　QUBE-Servo　2　equipped　with　an　inertial　disc　module.
