A preselector and an amplifier stage make up the RF portion. The RF amplifier determines the receiver's sensitivity. Because the RF amplifier is the first active device a received signal encounters, it is the principal source of noise and hence a major component in establishing the receiver's noise figure. Depending on the desired sensitivity, a receiver can have one or several RF amplifiers, or none at all. EXCEPT FOR ONE, there are several advantages to using RF amplifiers in a receiver. Select your answer. Image-frequency rejection is improved. Greater gain, therefore improved sensitivity High sensitivity and fidelity Enhanced signal-to-noise ratio

Obtaining broadband FM signal from narrowband frequency modulated (FM) signal is shown below. The narrowband FM signal has a maximum frequency deviation of 100 Hz. The frequency of the local oscillator is f0=100 kHz. Obtaining broadband FM signal from narrowband frequency modulated (FM) signal is shown below. The narrowband FM signal has a maximum frequency deviation of 100 Hz. The frequency of the local oscillator is f0=100 kHz.Since the broadband FM signal has a carrier frequency of fc=80 MHz, find the N value.
