- Please I need a 100 % correct answer some websites are answering the questions by using the frequency and some by using the effective aperture An antenna transmits a power of 2W from an antenna of 20db, towards a receiver located 40 km from the receiver, calculate the power received by an antenna of effective antenna 10 m^2 if the operating frequency is 11 KHzFind the effective value of a periodic current in a 20-ms period that has a value 0.761A for 4ms, 0A for 2ms, -0.925A for 8ms, and 1.23A for 6ms. Would the effective value be different if the time segments was in seconds instead of ms? Why?A satellite at an altitude of 37654 km transmits a signal of 17 GHz to a ground station directly below it. The following data is given. • Total atmospheric losses = 40dB • Transmit antenna gain = 55dBi • Receiver antenna gain = 60dBi • Signal to noise ratio of received signal = 6dB • Receiver signal noise power = 25pW • Receiver sensitivity = -90dBW I. Calculate the power transmitted. II. Find the Fade Margin for the link and comment on your result.

Compute ?(Ω) and plot its magnitude.The initals "Am" stand for amplitude modulation. Insted of fluctuating frequenices as above, they instead vary the amplitude, such that Y= A(t) sin [2pief]t. Notice that the frequency is now fixed, but the amplitude will be inconsistent. Each AM station is assigned a frequency in KHz (1,000 waves/second.) For example, 760AM is assigned a frequency of f=760kHz. What is the wavelength of the 760AM radio waves? Sketch of graph of y=2(exponent t) sin(t) and explain graphically what the amplitude is doing. The Bay of Fundy is between Maine and Nova Scotia, and it is famous for its high tides. There is a dock such that the water is 2ft deep at low tide and 58ft deep at high tide. High tide occurs 6 hours and 12 minutes after low tide. Draw a graph and create the equation that models that depth of water nd a function of time after high tide has occurred.
