Notes Principle of switching regulator A switching regulator creates a pulse train using a pulse width modulator. The above image depicts the fundamental circuit. When the drive pulse is strong, Q1 is saturated and receives ...
Notes TTL NAND gate In TTL device, each emitter acts as a diode, therefore, Q1 and 4kΩ resistor acts like a 2 -input AND gate. The rest of the circuit inverts the signal. The ...
Notes Operation of Master slave JK flip flop System To begin with the master is positive edge triggered and slave is negative edge triggered. Therefore, master responds to its J and k inputs before the slave.1. If J=1 ...
Notes Astable multivibrator The 555 timer is a TTL compatible integrated circuit and can be used as an oscillator to produce a clock wave. When the correct external components are connected, the circuit ...
Notes Working of a Monostable Multivibrator: The free running oscillator (stable) can be changed into a switching circuit having one stable and one quasi stable state. The resulting mono stable circuit is widely used in industry ...
Notes Shift Register A register is simply a group of flip flop that can be used to store a binary number. Each flip flop is capable of storing one bit information. A register ...
Notes Multiplexer A multiplexer (MUX) is a device that can synthesize a single output signal from multiple input signals in a way that is recoverable for each input signal. Data from multiple ...
Notes Voltage Gain of Single differential amplifier A single-ended differential amplifier is a circuit that amplifies the difference between two input signals, while rejecting any common mode signal that is present on both inputs.The voltage gain ...
