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
A. Stop band frequency
B. Pass band frequency
C. Centre band frequency
D. None of the mentioned
Answer:A

In a first order high pass filter, frequencies higher than low cut-off frequencies are called
A. Stop band frequency B. Pass band frequency C. Centre band frequency D. None of the mentioned
Explanation: Low cut-off frequency, fL is 0.707 times the pass band gain voltage. Therefore, frequencies above fL are pass band frequencies. 3. Compute the voltage gain for the following circuit with input frequency 1.5kHz.
