Question

The circuit shown in the figure below is called anRC high-pass filterbecause it transmits input voltage signals that have high frequencies with greater amplitude than it transmits input voltage signals that have low frequencies. If the input voltage is given byVin=Vin peakcos?t, then the output voltage isVout=VHcos(?t-?) where

1 + (?RC)?2 The circuit shown in the figure below is called anRC high-pass filterbecause it transmits input voltage signals that have high frequencies with greater amplitude than it transmits input voltage signals that have low frequencies. If the input voltage is given byVin=Vin peakcos?t, then the output voltage isVout=VHcos(?t-?) where VH=Vin peak/ Rot 1 + (?RC)?2 . (Assume that the output is connected to a load that draws only an insignificant amount of current.) Assume thatR=19k?andC=17nF. (a) At what frequency is VH= 1/ Root 2 Vin peak ? That particular frequency is known as the 3 dB frequency, orf3dBfor the circuit. kHz
