original: analog is usually thought of in an electrical context ; however , mechanical , pneumatic , hydraulic , and other systems may also convey analog signals .
simplifications: analog is usually thought of as being used with electrical systems ; however , mechanical , pneumatic , hydraulic , and other systems may also use analog signals . analog is usually thought of in electrical terms , but mechanical , pneumatic , hydraulic , and other systems may also send analog signals . analog is thought of in an electrical context however , mechanical , pneumatic , hydraulic and other systems may convey analog signals . analog is usually thought of in an electrical sense ; however , mechanical , pneumatic , hydraulic , and other systems may also send analog signals . analog is an electrical context although mechanical , pneumatic , and hydraulic may also convey analog signals . while analog is thought of electrically , mechanic , pneumatic , hydraulic and other systems may also use analog signals . analog is usually thought of in an electrical big picture ; however , mechanical , -lrb- air-related / air-operated -rrb- , liquid-related , and other systems may also bring across analog signals . analog is usually thought of in an electrical context ; however , mechanical , pneumatic , hydraulic and other systems may also convey analog signals .
