Pulse detection circuit

The pulse detection circuit uses an operational amplifier to form an in-phase AC amplifier circuit, which does not amplify the DC signal. Due to the presence of the feedback capacitor, it can filter out the power frequency interference of 50 Hz, so that the low frequency signal within 20 Hz passes smoothly, and multi-level amplification is performed, and then the density Special trigger shaping.

The SCSI interface is a general interface, which can connect the host adapter and eight SCSI peripheral controllers on the SCSI bus. The peripheral devices can include disk, tape, CD-ROM, rewritable optical disk drive, printer, scanner and communication equipment, etc.
● SCSI is a multi task interface with bus arbitration function. Multiple peripherals attached to a SCSI bus can work at the same time. Devices on the SCSI share the bus equally.
● the SCSI interface can transmit data synchronously or asynchronously, the synchronous transmission rate can reach 10MB / s, and the asynchronous transmission rate can reach 1.5mb/s.
● when the SCSI interface is connected to an external device, its connecting cable can be as long as 6m.
