Antenna is a Active or passive devices?
it depends on existing amplifier or not , if after antenna there's an amplifier it called active else it called passive which less sensitive that active .
What is a monolithic entity?
A monolithic entity is a type of integrated circuit used in electrical engineering. It has both active and passive devices.
What is active pull up in TTL NAND gate?
All standard TTL devices use a two transistor "totempole" output, one transistor provides an active pull down and the other an active pull up. Only one of these transistors is on at a time and one or the other is always on. Open collector TTL devices omit the active pull up transistor so that several outputs can be "wired" together and an external resistor provides a passive pull up. The only problem with this is the risetime of a passive pullup is much longer than the risetime of an active pull up, making the circuit slower. Tristate TTL devices have the same two transistor "totempole" output as standard TTL devices, but the circuits that control these transistors are more complex allowing a "third state" in which both transistors are turned off, leaving the output of the device floating. This allows many tristate TTL devices to be connected to a single line with only one actually driving it at a time (preventing conflicts with one device pulling up and another pulling down).
Why diode is active device when all other active devices require external power supply?
A Device is said to be active if... (i) It is a source of Power in the circuit... (ii) It amplifies any voltage or current in a circuit... (iii) It acts as a switch ie., has modes equivalent to ON and OFF... e.g., transistor amplifies and can also act as a switch...
Why do we need DC power supply for electronic devices?
Most active electronic devices (devices that amplify or switch states, e.g. vacuum tubes, transistors) only operate when conducting in one direction. If the current reversed periodically (as it does in AC) these devices would either not work at those times or would do something much different than they were designed to do. Thus DC is needed to keep them operating all the time.
What are the active electronic components?
Active devices are those devices which can produce power or which can amplify the signal Such devices are- diode transistor op-amp
What is transparent electronics?
The term transparent electronics refers to devices that has wide band gap semiconductors. The devices also contain active oxides in active components.
What is dynamic power dissipation?
It refers to transitional of active devices as opposed to steady state devices.
Are capacitors active or passsive devices?
A capacitor is to electricity as a glass is to water. Both are passive devices, they can be filled and they can be emptied.
What are dedicated devices in operating system?
Dedicated devices are devices that are assigned to only 1 job at a time and serves the job for the entire time it is active. eg. Printers, tape devices, plotters
Antenna is a Active or passive devices?
it depends on existing amplifier or not , if after antenna there's an amplifier it called active else it called passive which less sensitive that active .
What is the purpose of Exchange Active Sync?
There are many purposes of Exchange Active Sync. The main purpose of Exchange Active Sync is to allow all mobile devices to sync with Exchange accounts.

What three methods or devices are used to cool a CPU?
Passive and active air cooling and liquid cooling. What three methods or devices are used to cool a CPU
What is an active USB hub?
An active USB hub is a USB hub which has its own power supply. It will come with a DC power adaptor to power it. The USB system in your computer is capable of providing electrical power to devices which are plugged into it. When a large number of devices, or some particularly power-hungry devices are plugged into the USB system, it is possible to overexert this system. An active USB hub shores up this this power reducing the likelyhood of problems. A passive USB hub does not. Additionally, USB devices will often not work properly with more than 12 feet of cable. An active USB hub (or active USB extension cable) can help to overcome this limitation.
What are the advantages of an active adult community?
The active adult living community is desigend to keep the elderly active and socialize them together. While an independant living community will leave them to their own devices, and socialization practices.
Is a solar heating system that does not use fans or electrical devices an active solar heating system?
true
