WebElectrical noise is a high-frequency interference in the frequency spectrum of 7000 Hz to over 50 MHz. Noise can be transmitted and picked up by a power cord acting as an antenna, or it can be carried through the power line. These disturbances can be generated by radio frequency interference, such as radio, TV, cellular, and microwave ... WebNet gain/loss in a cascaded path can be calculated with simple addition/subtraction. Signal to noise ratio (in decibels) SNR dB = 10 log 10 (signal/noise) Note: “S/R” in the Shannon capacity formula is a normal ratio, not dB. See Example 3.6 in the textbook. 47 Exercises 48 Calculate the thermal noise for an effective noise
