Ee 341 Hw Pdf Frequency Modulation Computer Engineering It includes 6 questions related to frequency modulation (fm) and phase modulation (pm) of signals. question 1 asks to sketch pm and fm waves from a sawtooth modulation signal. question 2 gives an fm problem to calculate the modulation index, signal components, and bandwidth. 1 ee 341 fall 2005 2. problem 1.3 (d) (e) (f) (j). 3. problem 1.4 (b) (c). do part (e) for signals (b) and (c). 4. problem 1.7. do parts (a) and (b) for signals (b) and (d). 5. determine if the following signals are periodic. if they are, determine their fundamental period and fundamental frequency.
Modulation Lab1 Pdf Analog To Digital Converter Analogue Electronics When an inexpensive superheterodyne radio receiver (which has a poor selectivity in its rf stage bandpass filter) is tuned to 1500 khz, the signal is heard loud and clear. this same signal is also heard (not as well) at another dial setting. state, with reasons, at what frequency you will hear this station. the intermediate frequency (if) is. Question 2) [20pts] a carrier wave of frequency 100 mhz is frequency modulated by a sinusoidal wave of amplitude 20 v and frequency 100 khz. the frequency sensitivity of the modulator is 25 khz v. a) determine the approximate bandwidth of the fm wave, using carson’s rule. Be able to analytically describe and characterize a traveling plane wave with or without loss (amplitude, polarization, power density, frequency, wavelength, speed of propagation). Digital modulation techniques: basics of psk, ask, fsk, qam; ml demodulator implementation with matched filter, decision regions and probability of error analysis.
