3. The quality of a received signal is often characterized by the signal-to-noise-ratio (SNR), which is defined as SNR 10 log As you might expect from this Signal power in watts KTB definition, the unit of SNR is decibels (dB). The term in the denominator is the noise power, and it is generally specified as an effective noise temperature T multiplied by the product of Boltzmann's constant (K) and the bandwidth (B) of the signal in Hz. Generally we like...

Consider additive white Gaussian noise with a double-sided noise power spectral density (PSD) 12-90 dBm/Hz 1E-12 W/Hz. This noise corrupts a baseband polar NRZ signal with rectangular pulses, like that 1 mV and the pulse duration is Tb such that the symbol rate is Rb 1/Tb. Since this is binary signaling, the symbol rate equals the bit rate of the incoming baseband pulse train: B Rt. The signal is then sampled at the center of the noisy shown in the...
