History of Hybrid Computer
Packard Bell released the first-ever desktop hybrid computer which was the Hycomp 250. EAI launched another early hybrid computer in the year 1963 which was HYDAC 2400. Marconi Space and Defence Systems built the ‘Starglow Hybrid Computer’ in the 1980s combining three EAI 8812 analog computers, an EAI 8100 digital computer, and a SEL 3200 digital computer. Towards the end of late 20th century, hybrid computer usage decreased due to advancement of digital signal processors and digital computers.
What is Hybrid Computer?
Hybrid computer combines the features of digital computers with analog computers. The analog part works to solve differential equations and mathematical problems, whereas the digital part works as a controller and works on logical and numerical tasks. Therefore, a hybrid computer can easily function as and complete tasks of both analog and digital computers. Hybrid computers possess the valuable features of both these computer systems.
Features of a Hybrid Computer
The following are the main features of a hybrid computer:
Handling Large Equations: Hybrid computers easily manage large equations, producing exact results quickly.
Ready for use System: Hybrid computers are provided with cables and connections required in connecting to an analog computer. No more engineering is required.
Proven Performance: Around 150 applications and 100 hybrid systems use the PB250 computer.
Simple Expanded: The system includes built-in 64-channel address capabilities and modular plug-in construction. Hybrid computer offers a range of PB250 peripherals.
Types of Hybrid Computers
There are 3 types of Hybrid Computers:
General-purpose hybrid computer: Hybrid computers serve various purposes and can complete varied operations and problems. Initially, general-purpose hybrid computers mainly included high-performance computers and part-time hybrid computers
Large electronic hybrid computer: Large electronic hybrid computers were made from 1960 to 1980 by using hundreds of operational amplifiers. These computers have the capability to solve a wider range of differential equations because of hybrid construction.
Special-purpose hybrid computer: Their programs are integrated into a physical system to perform tasks such as analyzing results, controlling functions, or simulating subsystems, all preconfigured to address specific issues.
Examples of Hybrid Computer
Electrocardiogram Machine or ECG: ECG Machine used to monitor heart activity. Twelve to thirteen sensors are used to perceive bodily impulses and change them to digital data.
Forensics: Hybrid computers are also used for several forensic-related tasks. Using mass spectrometry to further understand a sample from any crime scene to measure the molecular mass of the element is an example of hybrid computer usage in forensics.
Monitoring Machine: The patient monitoring machine is used for measuring blood pressure, temperature, breathing rate, SPO2, heart rate, and other bodily functions.
Ultrasound Machine: Ultrasound machine uses high-frequency sound waves for medical purposes.
Advantages and Disadvantages of Hybrid Computer
The table below lists the advantages and disadvantages of a hybrid computer:
| Advantages of Hybrid Computer | Disadvantages of Hybrid Computer |
Speed: Computational speed is super fast which leads to exact and timely outcomes Precision: Provides precision, accuracy, details Complex Problem: Handles and solves complex equations in an instant Online Data Processing: Excels at real-time data analysis, finds results fast | Energy Usage: Consumes more energy to finish the same tasks while using analog circuits. Complex Setup: Setting up the needed hardware, software, and configuration settings in the design is complex Increased Cost: Not cost-efficient, are very expensive. Complexity: Hybrid computers are complex when compared to digital and analog computers |
