Fail-safe active bandpass filter using a modified twin-T filter |
摘要 |
A fail-safe active bandpass filter circuit is disclosed; that is, one having voltage gain and which is arranged to be fail-safe in the sense that opens, shorts and component value changes will not cause the circuit to self-oscillate and thereby produce a spurious signal that would cause unsafe effects.
