diode logic การใช้

• It also contained relay and diode logic for the automatic abort sequence.
• Another problem of diode logic is the internal resistance of the input voltage sources.
• Diode logic gates are implemented by passive elements; so, they have two restoration problems.
• Adding diode logic will degrade the signal level and result in poor noise rejection and possible failure.
• The Minuteman-II integrated circuits were diode-transistor logic and diode logic made by Texas Instruments.
• Diode logic is implemented by diodes which exhibit low impedance when forward biased and a very high impedance when reverse biased.
• The designer of a reliable diode logic circuit is usually limited to what the diode specification provides which is often less than the equation suggests.
• The first restoration problem of diode logic is that there is a voltage drop V F about 0.6 V across the forward-biased diode.
• Steele hired Donald Eckdahl, Hrant ( Harold ) Sarkinssian, and Richard Sprague to work on the MADIDDA's germanium diode logic circuits and also to do magnetic recording.
• Diode logic was used with vacuum tubes in the earliest electronic computers in the 1940s including ENIAC . Diode transistor logic ( DTL ) was used in the IBM 608 which was the first all-transistorized computer.
• There are two kinds of diode logic gates-OR and AND . It is not possible to construct NOT ( Invert ) diode gates because the NOT or Invert function requires an active component such as a transistor.
• The DTL circuit shown in the picture consists of three stages : an input diode logic stage ( D1, D2 and R1 ), an intermediate level shifting stage ( R3, R4 and V " ) and an output common-emitter amplifier stage ( Q1 and R2 ).
• In practice if the diode logic gate drives a transistor inverter, as it usually does, and the diode and transistor are of similar construction the transistor will have a similar base collector capacitance that is amplified by the transistor gain so that it will be too slow to pass the glitch.
• In the last two years, I revealed, in the introductory article parts, the fundamental ideas behind such legendary circuits as RTL, Diode logic, TTL, ECL, Latch, Gyrator, Schmitt trigger, Multivibrator, Differential amplifier, Operational amplifier ( the internal op-amp structure ).
• Per the discussion at Wikipedia : Reference desk / Science # Mickey Mouse Logic, the term appears to have an obscure definition that is unsuitable for expansion, and currently redirects to an article that doesn't mention it ( although I suppose the definition could be added to Diode logic if it's significant ) . talk ) 21 : 47, 7 March 2012 ( UTC)
