Hallo!
I need help please!
I have one equation about signals and system!
I hope the answer is clear writning.
This one!
A receiver can only record signals in the range 90 ≤ f ≤ 98
(MHz). We now want to transfer from a signal x (t) = sinω0t/
t.
This is multiplied by a high frequency carrier so that
we get the signal x̃ (t) = x (t) cosωct.
What is the maximum possible value for ω0 if all information in the
signal is to be recorded? Which one would we choose if ωc?

I NEED HELP IN THIS QUESTION ASAP PLEASE
A Transmitter provides 15 W to an antenna having 12 dB gain. The receiver Antenna has a gain of 3 dB and the receiver bandwidth BW is 30 kHz. If the receiver system noise figure F = 8 dB and the carrier frequency is 1800 MHz, Determine the maximum T-R separation that will ensure that a SNR of 20 dB is provided for 95% of the time. Assume n=4, 0 = 8...

1. In the lab we analyzed filtering 60 Hz power-line noise from ECG signal using a digital (signal processing) filter. Now let's try to an analog (circuit) filter approach to remove the 60 Hz line-noise. Following is an active twin-T notch filter with transfer function: (1+m)((2joRC? +1 Z(a) 2R 2R Here m is the ratio of the two feedback 2C R resistance which determines the gain and...
