One advantage is that the dB scale allows us to express … WebWhen RF elements are cascaded together, it becomes evident that instead of multiplying and dividing gain values, we can instead add or subtract them when they are expressed as dB. Gain can also be used to express a power level against an arbitrary reference value. crypto currency impact on indian economyWebMar 12, 2024 · Accepted Answer. The gain 50 dB is Receiver gain and 100MHz is the center frequency. The center frequency of a channel is measure of center frequency between upper and lower cutoff frequencies.It is usually defined as either the arithmetic mean or the geometric mean of the lower cutoff frequency and the upper cutoff frequency. crypto currency regulations in nigeria

"Webbypasses the RF signal around the emitter resistor to stop excessive RF gain degeneration in this circuit. The higher the voltage across R E (V E), the more temperature stable the amplifier, but the more power will be wasted in R E due to V E 2/R E, as well as the decreased AC signal gain if R E is not bypassed by a low reactance capacitor.
