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 an electrical term but mechanical, pneumatic, hydraulic, and other system have analog systems. Mechanical, pneumatic, hydraulic, and other systems may also send analog signals. Analog is considered electrical. Mechanical, pneumatic, hydraulic and other systems can send analog signals. Most people think of analog in an electrical setting. However, mechanical, pneumatic, hydraulic, and other systems can also send analog signals. Analog is usually thought of in an electrical context. However, mechanical, pneumatic, hydraulic, and other systems may also give analog signals. Analog signals are sent in more than just electrical systems. Analog is usually thought of in an electrical context. Other systems can also convey analog signals such as mechanical, pneumatic, hydraulic, and other systems. Analog is most used in an electrical speak, but mechanical, pneumatic, hydraulic, etc. may also convey these signals. Analog is usually thought of in an electrical context; however, analog signals can also be transmitted by mechanical, pneumatic, hydraulic and other systems. Analog is thought of in a electrical relation, but mechanical, pneumatic, hydraulic, and other systems may also carry analog signals.
