Explanation: High pass filter are often formed by interchanging frequency determining resistors and capacitors in low pass filters. For example, a first order high pass filter is formed from a first order low pass filter by inter changing components Rand C. 2. In a first order high pass filter, frequencies higher than low cut-off frequencies are called
