What is the difference between the net reproductive rate and the per capita rate of increase? the per capita rate of increase varies with environmental conditions, whereas the net reproductive rate does not the per capita rate of increase is an instantaneous rate, whereas the net reproductive rate is a generational growth rate the per capita rate of increase is only used in the geometric model, whereas the net reproductive rate can be used in both models the first two responses are both correct all of the above are correct

(d) One input to an AM DSBFC modulator is a 500 kHz carrier with an amplitude of 35 Vp-p. The second input is a 10 kHz modulating signal whose amplitude is sufficient to produce a 14 VP change in the amplitude of the envelope and the load resistance of the antenna is 10?. Determine i. The maximum and minimum positive AM envelope voltage. ii. The coefficient of modulation and percent modulation. iii. The total transmitted power. (e) Table (1) shows three superheterodyne receiver using high side injection that are receiving an AM DSBFC broadcasted signal from a radio station with RF carrier of 800 kHz and maximum modulating signal frequency of 5 kHz. Based on the given value of certain parameters for each receiver, i. Identify which receiver gives the best performance in teml of rejecting an image frequency signal from an undesired radio station. ii. How you relate the factor of distance between RF frequency and image frequency to your answer in i)? iii. As the receivers are tuned to several other radio stations, identify which receiver will be facing a problem in tracking each station carrier frequency if the maximum IF bandwidth is 15kHz. Table (1) Parameter Receiver A Receiver B Receiver C Preselector Q-factor 60 90 100 IF center frequency (kHz) 550 455 350 Tracking error range (kHz) ±2.5 ±1.5 ±3.5
