A high pass filter is a circuit that allows high frequency signals to pass through while attenuating low frequency signals.

• High pass filters are commonly used in audio systems to block out unwanted low frequency noise.

• The circuit diagram of a high pass filter typically consists of a resistor and a capacitor in series, with the output taken from the junction of the two components.

• The cutoff frequency of a high pass filt...read more

A full wave rectifier is an electronic circuit that converts alternating current (AC) to direct current (DC) by allowing both positive and negative half cycles of the input signal to pass through.

• Converts AC to DC by allowing both positive and negative half cycles to pass through

• Uses diodes to rectify the input signal

• Produces a smoother output compared to half wave rectifiers

• Commonly used in power supplies and battery
