What is Input Impedance? Input impedance refers to the equivalent impedance “seen” by a signal source when connected to the input of a circuit. It is a measure of how much the circuit resists or impedes the flow of current from the signal source. For an ideal operational amplifier (op […]

Introduction to Transistor Latches A transistor latch is a fundamental building block in digital electronics that can store one bit of information. It is a bistable multivibrator circuit, meaning it has two stable states and can remain in either state indefinitely until directed to change states by an input signal. […]
