The minimum received signal power level for which a receiver can produce a discernible output signal. The following equation for the sensitivity of a receiver shows the parameters that affect a receiving system's sensitivity
Indicates the sensitivity of a wireless receiver in picking up a good reliable signal from the matching wireless transmitter using the stock antenna. Sensitivity measurements of -75 dB and lower indicate very high gain potential for a wireless receiver. Recording Media refers to the magnetic storage device used to store recorded video. For many analog recorders this is a tape cassette, but DVR recorders use HDD hard disk drives. CDs and DVDs can also be types of media used to record digital video.
The ability of the receiver to pick up the weakest signal.
The ability of a receiver to differentiate a signal from the background noise.
Expressed in dBm this tells how much power the detector must receive to achieve a specific baseband performance, such as a specified bit error rate or signal to noise ratio.
A measurement of the weakest signal a device can receive and still correctly translate it into data. Also, the minimum required radio frequency (RF) signal power to meet a certain performance level. This level is referred to as the bit error rate (BER) and could be in the form of -80dBm or 0.000000010mW.
The degree to which a receiver can usefully detect a weak signal. The lower limit of useful signal input to the receiver.
The lowest level of signal that can be used for a given rate of errors. Dependant on speed of link. See Standards, Access Points and Cards.
The minimum received peak optical power that will produce a recovered electrical signal with minimal timing distortion.
Amount of power in dBm that a detector must receive to achieve a specific base band performance, such as a specified bit error rate or signal to noise ratio.
The minimum required RF signal power received to meet are certain performance level. This level is usually referred to as the Bit Error Rate (BER). Example: -80 dBm or 0.000000010 mW
The optical power required by a receiver for low error signal transmission. In the case of digital signal transmission, the mean optical power is usually quoted in Watts or dBm.
The minimum acceptable value of received power needed to achieve an acceptable BER or performance. It takes into account power penalties caused by use of a transmitter with worst-case values of extinction ratio, jitter, pulse rise times and fall times, optical return loss, receiver connector degradations, and measurement tolerances. The receiver sensitivity does not include power penalties associated with dispersion, or backreflections from the optical path; these effects are specified separately in the allocation of maximum optical path penalty. Sensitivity usually takes into account worst-case operating and end-of-life (EOL) conditions.
Measure of power needed by the detector to achieve a specific baseband performance, such as a specified bit error rate or S/N ratio.
The minimum acceptable value of average received power at point R to achieve a 10 bit error ratio. It takes into account power penalties caused by use of a transmitter with worst-case values of extinction ratio, jitter, pulse rise and fall times, optical return loss at point S, receiver connector degradations, and measurement tolerances. The receiver sensitivity does not include power penalties associated with dispersion, jitter, or reflections from the optical path; these effects are specified separately in the allocation of maximum optical path penalty. Sensitivity takes into account worst-case operating and end-of-life (EOF) conditions.
