What is analog computer?
An analog computer refers to a computer that uses the continuously changeable aspects of physical phenomena such as electrical, mechanical, or hydraulic quantities to model the problem being solved. In contrast, digital computers represent varying quantities symbolically, as their numerical values change.

The first known analog computer is believed to have been built before 100 BC, it is unknown when it was invented.

An analog computer does not use discrete steps, but smoothly models whatever is being calculated. Most are specialized devices, but the (good old) slide rule was a general pur…pose analog computer. It's one great advantage is speed, and high speed digital computers have mainly taken over.

well..i think it would have to be a remote of some kind
The Antikythera mechanism (pronounced /ËÃ¦ntÉªkÉªËÎ¸ÉªÉrÉ/ AN-ti-ki-THEER-É ), is conjectured to be an ancient mechanical computer   design…ed to calculate astronomical positions. It was recovered in 1900-01 from the Antikythera wreck,  but its complexity and significance were not understood until decades later. It is now thought to have been built about 150-100 BC. Technological artifacts of similar complexity did not reappear until the 14th century, when mechanical astronomical clocks appeared in Europe.
it can be small, it can be large. The critical question is how many integrators does your problem need?
The first known analog computer is the antikythera mechanism. It was found underwater in 1900. It is believed to have been made prior to 100BC. Inventor unknown.
It not analog , its digital. Analog devices are continuous , digital devices have discontinuous states . As the only valid states of an abacus have each bead either up or d…own (never in the middle) it has discontinuous states and is digital.
depends, it can be as small as a Nordon bombsight or as large as one wall of a room. some have been smaller or bigger than that range.
Mechanical ones were built as far back as 100BC. The Bush Differential Analyzer was a large programmable electromechanical analog computer built starting in 1929. The famous …Norden Bombsight of WW2 was an electromechanical analog computer designed in the 1930s and built through much of the 1950s, when electronic analog computer bombsights replaced it. Electronic ones were built from the 1930s through the 1970s.
The Antikythera mechanism is believed to be the earliest known mechanical analog "computer" by Derek J. de Solla Price. It was designed to calculate astronomical positions. …It was discovered in 1901 in the Antikythera wreck off the Greek island of Antikythera, between Kythera and Crete, and has been dated to circa 100 BC. Devices of a level of complexity comparable to that of the Antikythera mechanism would not reappear until a thousand years later.
It works on a constant supply of varying signals (and not necessarily even electrical). For instance, an automatic transmission in a car is pretty much an analog computer. As …the pressure of the pump and the signals on the governor and modulator valve vary, the fluid goes through different valves in the control body and controls which transmission bands are applied at what particular time. The more sophisticated of the mechanical clocks are also analog computers, as well as the old adding machines. Gears and tumblers had to make up for a lack of circuitry.
