11. In most receivers this is accomplished by a bandpass filter in the RF front end. 12. A modulator and carrier signal are sent through a series of these tuned bandpass filters . 13. Hence, one may correctly say'A dual bandpass filter has two passbands '. 14. Such a crossover would then have a bandpass filter for the lowest-frequency driver. 15. Tunable RF bandpass filters offer a significant size reduction over switched RF bandpass filter banks. 16. Tunable RF bandpass filters offer a significant size reduction over switched RF bandpass filter banks. 17. A bandpass filter is utilized to extract the oscillometric pulses from the cuff deflation curve. 18. In many tunable receivers, the bandpass filter is tuned in tandem with the local oscillator. 19. Therefore, the superheterodyne requires a bandpass filter on the input to reject this image frequency. 20. All the transmittances H 1-H 4, in this example, are bandpass filters .
