1. After conversion to the intermediate frequency, the signal is amplified in several IF-amplifier stages.

2. Narrow-band selection (13, 19) is not carried out in the baseband but on an intermediate frequency level above the baseband.

3. 10 It includes four basic elements:user interface, GPS signal simulator(intermediate frequency, IF), civilian(C/A) software receiver and interference generator.

4. Radio frequency (RF) and intermediate frequency (IF) transceiver circuit assemblies, and analog and digital signal processing circuit assemblies for wireless communication apparatus

5. For example, a key component of a superheterodyne receiver is a mixer used to move received signals to a common intermediate frequency.

6. The mixer is called the first detector, while the demodulator that extracts the audio signal from the intermediate frequency is called the second detector.

7. Upgraded 1DD+1BA Hybrid Earphones & Magnetic Dynamic Unit with features self-customized balanced armatures which includes 9.2mm super bass single dynamic Driver + 1 intermediate frequency Balanced Armatured .

8. Without an internal calibration system special attention was paid to local oscillator's coherency and intermediate frequency (IF) filter's selection. These represent two of the main sources of error between adjacent channels.
