Characterize Op-Amp based filters by plotting their frequency and phase response

A multiple feedback band-pass filter centered around 1500Hz is studied between 1KHz and 2KHz . The circuit was simulated using online tools from Okawa Denshi corp

 

Frequency response of a piezo buzzer. The buzzer has a plateau like response between 3.3KHz and 3.7KHz
