Ans. -119.3 dBm . Signal to Noise Ratio (SNR) Receiver sensitivity is a measure of the ability of a receiver to demodulate and get information from a weak signal. We quantify sensitivity as the lowest signal power level from which we can get useful information.

Webb17 nov. 2024 · This allows filters and amplifiers designed to operate at a fixed IF to be used across the whole range. Making the bandwidth of this IF section smaller lets you … Intermediate frequencies are used for three general reasons. At very high (gigahertz) frequencies, signal processing circuitry performs poorly. Active devices such as transistors cannot deliver much amplification (gain). Ordinary circuits using capacitors and inductors must be replaced with cumbersome high frequency techniques such as striplines and waveguides. So a high frequency signal is converted to a lower IF for more convenient processing. For example, in satellite dishes, …
