Direct band semconductors are mostly for LEDs. Indirect band semiconductors like Si and Ge are conventional diodes.
-- There's no such thing as 'indirect' current.-- Direct current has no frequency. As soon as you mention 'frequency',you're talking about alternating current.
Silicon is an indirect band gap semiconductor
A transistor in the right circuit, contributes a POWER GAIN by taking energy from an external power supply. A transformer actually has losses but is primarily used for Impedance Matching. This is very useful in establishing the most efficient arrangements for transmitting power from the source to the load. Impedance matching is an important function of all power transfer systems.
Telestimulation systems are described for chronic indirect muscle stimulation in caged rabbits and mice. Both system use a 5 MHz carrier frequency transmission and consist of a transmitter and a receiver. The latter is fixed to the back of the animal.
Direct is an exact measurement and indirect is an estimate.
Direct Measurement: Apply the instrument directly to the unknown quantity. E.g. Taped distance, direction measured with a theodolite Indirect Measurement: Determined from its relationship to direct measurements. E.g. height difference determination in trigonometric leveling
Both are measurements of the saturation of hemoglobin with oxygen in arterial blood.The difference is how the measurement is taken SpO2 is an indirect measurement using a finger probe, ear sensor or similar device. SaO2 is a direct measurement using a blood sample such as an arterial blood gas analysis.
there are two types linears measurements 1)direct 2) indirect
The idea is that you model a situation with similar triangles and then use proportions to find the missing measurement indirectly.
Indirect measurement is a technique that uses proportions to find a measurement when direct measurement is not possible.
An indirect measurement of the speed of molecules is made with a thermometer.
Indirect measurement is a measurement that is not obtained from a measurement tool; it is a technique that obtains a measurement when direct measurement is not possible. In software metrics work, indirect measures associate a measure to a feature of the object being measured. An example is basing quality on counting rejects. Indirect measures include functionality, quality, complexity, efficiency, reliability, and maintainability.
The temperature.
The speed of molecules.
NO
When instead of measuring the specific thing directly you measure some other aspect of the event and from that figure out the actual value. Ex. Lets say that you need to find out the height of a tower, but that you can not measure it from top to bottom with a measuring tape. You can measure the shadow on the ground and with knowledge of the suns position and the angle of the shadow calculate the height of the tower.
