Signals and amplifiers cover frequency spectrum and basic circuit models. Operational amplifiers include inverting and noninverting configurations. Semiconductors discuss intrinsic and doped types and current flow. Diodes cover rectifier circuits and various applications. MOSFETs and BJTs provide detailed transistor operation and characteristics
Comparator compares two voltages and outputs digital signal indicating larger value. Consists of high-gain differential amplifier with two analog inputs. Output is either 1 (plus side) or 0 (negative side)

TTL was invented by James L. Buie in 1961 as transistor-coupled transistor logic. First commercial TTL devices were manufactured by Sylvania in 1963. Texas Instruments introduced 7400 series in 1966, becoming industry standard. TTL became foundation of computers and digital electronics
Boolean Algebra was developed by George Boole in 1854. Truth values represent logical propositions using only True and False. Truth values can be represented using 0 (False) and 1 (True)
Decoder converts digital signals into corresponding decimal code. It is the most commonly used circuit before encoders. Decoder accepts binary code as input, unlike encoder
