3. A Superheterodyne receiver uses high side injection. The receiver is to tune the RF range 500kHz to 1750kHz. The IF is 400kHz. Calculate a. the local oscillator capacitance tuning ratio b. if the receiver is tuned to 1000kHz, calculate IFRR (in dB) if Q=100 c. If the IF is adjusted to 300kHz, and the receiver is tuned to 1000kHz, calculate IFRR(in dB) if Q=100 d. Between IF of 300kHz and IF of 400kHz, which is better? Why?
