Product Description

Two stage RC Coupled Transistor Amplifier (Frequency Response)

Objective : To study Frequency Response of Single stage two stage RC coupled Common Emitter Transistor Amplifier.

Features : Instrument comprises of DC Regulated Power Supply, Circuit diagram is printed, components mounted on the front panel.

Robust Two-Stage RC Coupled Design

This amplifier utilizes a classic two-stage RC coupled architecture, allowing effective signal amplification across the 20 Hz to 20 kHz frequency spectrum. Each stage employs a BC547 or similar NPN transistor, with carefully chosen coupling capacitors for optimal frequency response.

User-Friendly and Educational

Engineered for electronics laboratories and training settings, the amplifier offers easy PCB mounting through drilled holes, as well as clear soldered pin terminals. Its straightforward topology supports hands-on learning and demonstration of signal amplification and phase shift concepts.

Clean Performance for Audio Applications

Delivering over 100x gain at mid frequencies, the unit supports clean audio preamplification with low noise (1 mV at output) and less than 2% harmonic distortion. It can effectively drive loads between 1 k and 10 k, making it suitable for a variety of audio and measurement experiments.

FAQs of Two Stage RC Coupled Transistor amplifier:

Q: How is the Two Stage RC Coupled Transistor Amplifier connected in an experimental setup?

A: The amplifier features soldered pin terminals for input, output, and power connections, facilitating straightforward integration into lab experiments. Simply connect your signal source to the input terminal, the output load to the output terminal, and a 9V DC supply to the power pins.

Q: What types of experiments or demonstrations can this amplifier support?

A: It is ideal for audio preamplification demonstrations, investigation of phase shifts, gain measurement, and other signal amplification studies in electronic training labs. The mono channel and wide frequency response make it suitable for exploring basic audio circuit principles.

Q: When should the recommended load impedance range (1 k 10 k) be observed?

A: For best performance and to maintain signal integrity, ensure that the output load falls between 1 k and 10 k. Loads in this range optimize gain and minimize distortion, especially during audio and measurement experiments.

Q: Where can this amplifier be mounted within a laboratory setup?

A: Designed with drilled holes for fixed PCB mounting, the amplifier can be securely positioned on experiment boards, lab training panels, or inside equipment housings as needed. The compact form factor (150 mm x 100 mm x 40 mm) allows versatile placement.

Q: What is the typical signal input level and what benefit does the amplifier provide in audio applications?

A: Accepting input signals from 10 mV to 60 mV (peak-to-peak), the amplifier boosts weak audio or test signals for easier observation or further processing. Its high signal-to-noise ratio (>60 dB) ensures amplified output with minimal background noise.

Q: How does the phase shift characteristic of this amplifier function?

A: Each RC coupled stage introduces a 180 phase shift, resulting in a total of 360 shift across both stages. This property can be demonstrated and analyzed in classroom or lab environments to illustrate signal inversion and amplification principles.
