Variable Low-Pass Filter Circuit
This second-order low-pass filter utilizes a 741 operational amplifier and can be tuned from 2.5 kHz to 25 kHz. The circuit is beneficial in audio and tone control applications. R1 and R2 are ganged potentiometers.
The described circuit features a second-order...
12dB / Octave Linkwitz Riley Crossover
The circuit diagram of the filter section is shown in Figure 1. It is a completely conventional filter, and the component designations are the same as for the 24dB unit described in Project 09. It is designed primarily for 2-way...
Overview of 2.1 (Satellite/Subwoofer) Speaker Systems
This application note explains how to implement a 2.1 (satellite/subwoofer) audio power-amplifier system with 2 x 2W and 1 x 7W of output power from a single 5V power supply.
The described 2.1 audio power-amplifier system is designed to deliver a...
Programmable Frequency Divider
This divider utilizes a variable-length shift register, a type-D flip-flop, and an inverter. The clock signal is connected to the clock input of the flip-flop, while the output of the shift register is connected to the D input of the...
5-Pole Low-Pass Filter Circuit
The LTC1063 is a monolithic low-pass filter that provides exceptional DC and AC performance. It features both internal and external clock tunability, with cutoff frequencies reaching up to 50 kHz, a typical output DC offset of 1 mV, and a...
Low-pass filter
This circuit is useful where fast signal acquisition and high precision are required, such as in electronic scales. The filter's time constant is determined by the 2-ohm resistor and the 1 µF capacitor until comparator No. 1 activates. After this...
Speaker Microphone Schematic
This circuit allows the use of a low-cost loudspeaker as a microphone. Sound waves that reach the speaker cone cause fluctuations in the voice coil. The movement of the voice coil within the speaker's magnetic field generates a small electrical...
Voltage Controlled Frequency Divider with Variable Division Ratio
This voltage-controlled frequency divider circuit produces lower frequency pulses that depend on the control voltage, with synchronous rising edges for the input and output pulses. Typically, such frequency dividers utilize a monostable circuit connected between an inverted output and the...
Speaker to microphone converter circuit
This circuit provides a straightforward method for converting a loudspeaker into a microphone. When sound waves impact the diaphragm of the speaker, fluctuations occur in the coil, generating a small induced voltage that is typically low in magnitude and not...
