[15 points] You are asked to design a DSB-SC AM modulator to generate a modulated signal km(t)cos(wt+0), where m(t) is a signal band-limited to B Hz. The following figure shows a DSB- SC AM modulator available in the stockroom. The carrier generator available generates not cos(wct), but cos (wct). Explain whether you would be able to generate the desired signal using only this equipment. You may use any kind of filter you like. 3. What kind of filter is required...

Please answer these 4 questions because they are related to each other. Thanks:) Question 2 (Total 20 marks) (a) Given an AM signal Vam (t)=5[10+ cos(1000xt) ]cos(30000īt) volts is fed to a 1000 load. Determine (i) the average power in the carrier; (ii) the average power in the upper sideband (iii) the ratio of the power in sidebands to the power in the carrier. (6 marks) (b) For the AM signal given in part (a), sketch its double-sided amplitude spectrum...
DO NOT SOLVE THE QUESTION! THAT IS NOT WHAT I AM ASKING. THIS IS THE SECOND TIME I AM POSTING THIS Q BECAUSE THEY DID NOT ANSWER MY Q. I just want to know for 1a, answer is a bandpass filter. Can a LOW PASS FILTER also work? You are asked to design a DSB-SC modulator to generate a modulated signal km(t) cos(w m(t) is a signal bandlimited to B Hz. Figure 1 shows a DSB-SC modulator available in the...
can someone help me do this and maybe also the picture of the scope explain how you get it. thankyou! Frequency-shift keying (FSK) and Phase-shift keying (PSK) Two other modulation schemes are the phase-shift keying (PSK) and the frequency-shift keying (FSK). These are illustrated in Figure 8 b and c respectively. In phase-shift keying the carrier signal changes phase by a radians when the digital signal changes values. In frequency-shift keying a 0 is transmitted at a different carrier frequency...

Please do Part 4 and Show all work! 1. 145 points) <FM/FSK Modulation/Demodulations A periodic wave m(t) in Figure 1 below The resulting FM signal is demodulated as shown in the following figure by using frequency discriminator. Assume no attenuation of the signal due to propagation loss (in other words assume amplifiers properly restored the amplitude of the transmitted signal at the receiver) [10 points] Find the Fourier Series (trigonometric Fourier Series) of the message signal m (t) where To...
Question 4 (a) Find the DFT of the series x[n)-(0.2,1,1,0.2), and sketch the magnitude of the resulting spectral components [10 marks] (b) For a discrete impulse response, h[n], that is symmetric about the origin, the spectral coefficients of the signal, H(k), can be obtained by use of the DFT He- H(k)- H-(N-1)/2 Conversely, if the spectral coefficients, H(k), are known (and are even and symmetrical about k-0), the original signal, h[n], can be reconstituted using the inverse DFT 1 (N-D/2...
