RSSI is an indication of the power level being received by the receiving radio after the antenna and possible cable loss. Therefore, the greater the RSSI value, the stronger the signal. Thus, when an RSSI value is represented in a negative form (e.g. −100), the closer the value is to 0, the stronger the received signal has been.
The carrier-to-receiver noise density ratio is usually expressed in dB-Hz. The noise power density, N 0 = kT , is the receiver noise power per hertz , which can be written in terms of the Boltzmann constant k (in joules per kelvin ) and the noise temperature T (in kelvins).
For 2017, Harley released the Street Rod based on the 750 Street model. This new model introduced new features such as higher output Revolution X engine 68.4 hp (51.0 kW) @ 8,750 rpm and 47.2 lb⋅ft (64.0 N⋅m) @ 4,000 rpm, 43 mm inverted front forks and piggyback reservoir rear shocks, drag-style bars and 17 inch wheels.

For example, a receiver sensitivity of −98 dBm is better than a receive sensitivity of −95 dBm by 3 dB, or a factor of two. In other words, at a specified data rate, a receiver with a −98 dBm sensitivity can hear signals that are half the power of those heard by a receiver with a −95 dBm receiver sensitivity. [citation needed].
The two standards are only slightly different, with receivers able to work with either system with only minor inconsistencies in the displayed data. Both versions carry data at 1,187.5 bits per second (about 1.2 kbit/s ) on a 57 kHz subcarrier , so there are exactly 48 cycles of subcarrier during every data bit.
In order to achieve both good adjacent channel selectivity and image rejection, the double-conversion receiver uses two intermediate frequencies (IFs). The incoming radio frequency (RF) signal from the antenna is first mixed with a sinusoidal signal from the 1st local oscillator (LO) to give a high 1st IF frequency. Since the separation between ...
