1. If an odd-ordered active high-pass filter is to be implemented then we need a first a simple firstorder RC circuit and a buffer. Give this RC circuit along with the buffer
2. Find an active RC high-pass filter with a 3 dB cut-off rerquency of 2π(200). At the edge of the stop band at 2 π (60), the attenuation must be at least 20 dB.
