Electronic Circuit on Perfboard, San Francisco State College (Alternate View)

About This Item

A small electronic circuit assembled on a perforated prototyping board (perfboard) is shown, featuring discrete components such as resistors, capacitors, and an integrated circuit. The arrangement illustrates hands-on circuit construction and testing in an electronics laboratory setting.

Identifier
TP-ATA-1888
Context

Function: Analog Comparator or Timing Circuit

This board is a more refined prototype. From the visible components, it looks like it could be:

  • A voltage comparator or basic timer circuit

  • Possibly part of a:

    • Voltage threshold trigger

    • Stability monitoring unit

    • Or even a low-frequency oscillator

Visible Components:

  • IC (Integrated Circuit): Likely an op-amp or comparator (LM741 or similar)
  • Resistors: Used for biasing or voltage division
  • Capacitor: Timing or smoothing function
  • Transistors: Switching control (may serve as an output driver)
