100 Watt power attenuator. An attenuator is a passive broadband electronic device that reduces the power of a signal without appreciably distorting its waveform. An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than ...
The decibel originates from methods used to quantify signal loss in telegraph and telephone circuits. Until the mid-1920s, the unit for loss was miles of standard cable (MSC). 1 MSC corresponded to the loss of power over one mile (approximately 1.6 km) of standard telephone cable at a frequency of 5000 radians per second (795.8 Hz), and matched closely the smallest attenuation detectable to a ...
In engineering, attenuation is usually measured in units of decibels per unit length of medium (dB/cm, dB/km, etc.) and is represented by the attenuation coefficient of the medium in question. [1] Attenuation also occurs in earthquakes; when the seismic waves move farther away from the hypocenter, they grow smaller as they are attenuated by the ...
For instance, if stage 1 represents a 6 dB attenuator so that =, then = + +. Effectively the noise temperature of the amplifier T 2 {\displaystyle T_{2}} has been quadrupled, in addition to the (smaller) contribution due to the attenuator itself T 1 {\displaystyle T_{1}} (usually room temperature if the attenuator is composed of resistors ).
Fair Market Rent in the US context is the amount of money that a given property would command, if it were open for leasing at the moment.. Fair market rent is an important concept both in the Housing and Urban Development's ability to determine how much of the rent is covered by the government for those tenants who are part of Section 8, as well as by other governmental institutions.
Net Effective Rent, sometimes Net Effective Rate, or NER for short, is a measure of the expected income from a tenant, seen mostly in commercial real estate. It is the net present value of all the rental payments over the period of the lease, as well as any abatements or incentives that might add to or lower these payments. An example of a ...
Real estate benchmarking is the standard of measurement used to analyze the financial characteristics of a real estate investment property. In the general sense, real estate benchmarking refers to the comparison of potential real estate investment properties against a predetermined framework of measurement. In a narrow sense, the term real ...
Imputed rent is the rental price an individual would pay for an asset they own. The concept applies to any capital good, but it is most commonly used in housing markets to measure the rent homeowners would pay for a housing unit equivalent to the one they own. Imputing housing rent is necessary to measure economic activity in national accounts ...
