An amplifier has cutoff frequencies fc1 = 1.2 kHzand fc2 = 16.4 kHz. Calculate theBandwidth. BW = fc2-fc1=16.4 kHz-1.2 kHz = 15.2kHzList the characteristics of an ideal op-amp.An amplifier has cutoff frequencies fc1 =1.2 kHz and fc2 = 16.4 kHz. Calculate the Bandwidth. List the names of the active filters by their voltage gain(dB) vs frequency graphs.
Calculate the E-field generated at all points by concentric spheres of surface charge that are centered at the origin. Assume that inner and outer sphers have radii ra and rb and surface charge densities Psa and Psb, respectively.
Design a cascade of two lowpass L-networks to optimally mathc Rs=50 ohm to RL = 5k ohms at 10MHz frequency. Choose network parameters to maximize overall bandwidth.
