Communication System Solve with ALL steps Please QUESTION 3 Briefly explain the following Analog Pulse Modulation (APM): (i) Pulse Amplitude Modulation (PAM) Pulse Width Modulation (PWM) (iii) Pulse Position Modulation (PPM) (2 marks) (2 marks) (2 marks) b) There are several digital modulations techniques used to modulate digital signal. For a binary data 10111011, sketch the output waveform if the following modulator is used: Amplitude Shift Keying (ASK) (2 marks) Frequency Shift Keying(FSK) (2 marks) (iii) Phase Shift Keying (PSK)...
please type the answer....No Hand writting please Two types of digital-to-analog modulation techniques are Amplitude Shift Keying (ASK) and Frequency Shift Keying (FSK). In ASK, two different amplitudes, and only two, represent the digital information. In FSK, only two different frequencies are used to represent the digital data. The Goal The goal of the design project is to design a Commsim circuit that will generate the following analog carrier based on a digital input stream: Output 2 0 -1 -2...
2) A wireless internet access card requires for reliable operation the BER not exceeding 10-3. An engineer designing this card wishes to maximize the data rate over the SNR range of 0 to 20 dB. Select a proper modulation format for cach SNR at this range. Hint: M-ary constellation, such as M-QAM is a good candidate, with M-2 1-2,3,4... , for which you have to find a threshold SNR Yh(M) such that Pe(SNR,M)s10-3 if SNR 2Yth(M) , where Pe (SNR,M)...
