Assume that we want to register all 2-digit info on LED display every 250ms such that there will be no lost data during screening. Output stage of camera will feed transceiver unit. 88 There is a LED screen and 2-digit codes are present on it There is a 50x50 matrix pixel set is on the screen. When digits are on, other pixels on the LED are dark. In case where two digits numbers are illuminated only a 50% of all pixels for worst case are in use. 2-digit code on the display changes every half seconds. Between two succeeding frames there is 10ms of NULL. A 10x10=100 pixel resolution camera is taking pictures of LED display simultaneously. It sub-stores images during 2,070 seconds. Note that, between each frame, there is 10ms of NULL. • By then, it feeds the transceiver unit by 2, 070 seconds length multi-frames. A camera to be used supports up to 64bits in colour and brightness. • Expected SNR through the system is at least 30dB. o All other conditions are assumed as perfect and as it is expected. Ignore un-expected problems rather than declared above. Q1(50P) AM modulator and demodulator couples based on following rules will be used transfer to above 2-digit camera pictures from one location to another one. Design Principles: 1- bandwidth of filter you will design will be 12kHz in case of double sideband solutions. 2- carrier frequency will be 11MHZ. 3- Amplitude of message signal will be 34 (mV) 4- Amplitude of carrier signal will be 33 (mV) a) Design and determine the values of all elements in transceiver couple. All values must be proved by mathematical calculations. b) Check the possibility of your design either it will allow you to transfer a multi-frame. c) If not, please offer a method to transfer a useful data without missing any info. d) Discuss problems related to modulated index, if any. rofess UEE Q2(50P) A narrow band FM modulator and demodulator couples based on following rules will be used transfer to above 2-digit camera pictures. Design Principles: 1- bandwidth of message signal will be 6 kHz in case of double sideband solutions. 2- Means carrier frequency will be 40 MHz. 3- Allowable maximum frequency deviation of the system is 50kHz. 4 - B = 0.03 a) Design and determine the values of all elements in transceiver couple. All values must be proved by mathematical calculations. b) Check the possibility your design couple either it will allow you to transfer multi-frame. c) If not, please offer a method to transfer a useful data without missing any info. d) Discuss if you meet any contradiction between calculated modulation index and common design requirements. fes mUEE Assume that we want to register all 2-digit info on LED display every 250ms such that there will be no lost data during screening.
